Lenovo's T-series ThinkPads laptop are designed to offer mobile professionals an appealing combination of performance and portability, wrapped up in the familiar durable ThinkPad design. The slimline 14in. T420s features Sandy Bridge processors and optional dual-mode integrated/discrete graphics, along with additions (under the banner Enhanced Experience 2.0 for Windows 7) such as rapid boot-up and shutdown. As with all ThinkPads, there's also a veritable arsenal of ThinkVantage Tools that help to keep the system secure and up-to-date.

Design

The black-clad T420s looks every inch a ThinkPad, its standout visual features being the 14in. 1,600-by-900-pixel screen (which is LED-backlit and pleasingly non-glossy) and the traditional (non-isolation-style) keyboard.

The T420s is also noticeably slim for a full-featured business notebook at just 2.1-2.59cm, while the footprint, at 34cm wide by 23cm deep, means it should fit comfortably into most laptop bags. Sturdy construction and a solid two-point screen clasp should keep safe and sound in transit.

There's little flex in the lid section, and the keyboard feels admirably firm when you're typing. The system weighs a very manageable 1.78kg with an optical drive in the modular bay (as in our review unit), and the 90W power brick is reasonably compact.

We've used plenty of 'modern', MacBook-imitating isolation-style keyboards, and some (including those on Lenovo's own ThinkPad Edge series) are perfectly usable. But given the choice, we'd select the traditional ThinkPad keyboard, as seen on the T420s, every time. In terms of feel and layout, it simply cannot be beaten, in our opinion. There's no backlight, but you do get the Fn+PgUp-toggled ThinkLight that shines down from the top of the lid to help you work in dimly-lit conditions.

We've also used plenty of pointing sticks from other vendors, but few compare to those from its inventor. You get three buttons with the trackpoint (right and left mouse, plus scroll), and two with the stipple-surfaced touchpad, which has built-in vertical and horizontal scroll zones. The wrist-rest area has a fingerprint reader on the right-hand side, above the ThinkPad logo.

Features

Our review sample of the ThinkPad T420s was powered by Intel's quad-core Core i7-2640M processor running at 2.8GHz (3.5GHz with Turbo Boost), supported by 4GB of DDR3 RAM. Up to 8GB of memory is supported, by filling both DIMM slots with 4GB RAM modules. A more affordable Core i5-2520M-based system is also available on Lenovo's UK web site, and you can customise the detailed configuration of both models.

The review unit was equipped with both discrete and integrated graphics, in the shape of Nvidia's NVS 4200M GPU with 1GB of dedicated DDR3 video memory and Intel's CPU-integrated HD Graphics 3000, which can dynamically command between 64MB and 1,696MB of system memory for its purposes. The NVS 4200M supports Nvidia's Optimus technology, which automatically switches between discrete and integrated graphics according to the workload, maximising battery life by not using a high-power GPU for low-end tasks.

Storage comes in the form of a fast, low-power 160GB Intel solid-state drive (SSD). This is an expensive option, and you can specify lower-capacity 128GB SSD for £79.80 (ex. VAT) less, or a 320GB, 7,200rpm hard drive for £214.12 (ex. VAT) less.

Connectivity options are excellent, our review sample not only featuring dual-band Wi-Fi (802.11a/b/g/n) and Bluetooth (3.0), but also HSPA mobile broadband (Ericsson F5521gw). Among the ThinkVantage Tools you'll find a Mobile Broadband Activate utility to set the connection when you insert your SIM. There's Gigabit Ethernet for wired networking too, of course.

You get a reasonable selection of ports and connectors on the T420s, but many users will want to add a port replicator or a docking station for extra features and in-office convenience.

The left-hand side has a USB 2.0 port and a 34mm ExpressCard slot, while the right-hand side is taken up mostly by a modular Ultrabay, fitted with an optical drive in our review unit. If you want the full claimed 10-hour battery life, you can replace the optical drive with a second 3-cell Ultrabay for an extra £68.40 (inc. VAT) to complement the system's primary 6-cell battery.

At the back, from left to right, there's an RJ-45 (Ethernet) port, a USB 3.0 port, a sleep-and-charge USB 2.0 port, a DisplayPort and a 15-pin VGA port.

If you want to keep network and external monitor connections in place in the office, a ThinkPad Port Replicator Series 3 with Ethernet, four USB 2.0 ports and a VGA connector will cost you £107.35 (ex. VAT) extra. A Mini Dock Series 3 with Ethernet, six USB 2.0 ports, VGA, DVI and DisplayPort connectors, plus a pair of audio jacks costs £178.60 (ex. VAT).

Other noteworthy features include a 720p HD webcam and a dual array microphone in the top screen bezel, and a pair of stereo speakers flanking the keyboard. These can be configured using the Communications Utility in ThinkVantage Tools, which includes useful settings such as microphone optimisation for single or multiple voices, keyboard noise suppression and single or multiple audio streams (over speakers and headphones).

Performance & battery life

Lenovo sets great store by the speed with which the ThinkPad T420s boots into Windows 7, claiming this can be achieved "in as fast as 10 seconds". Our review sample didn't show such eagerness to get Windows going, but booted up in a perfectly acceptable 30 seconds on average. It was quicker to exit Microsoft's OS though, taking just under 10 seconds to shut down.

WEI (Windows Experience Index) scores for the ThinkPad T420s ranged between a middling 4.7 (out of 7.9) for Graphics (Desktop performance for Windows Aero) and an impressive 7.5 for Primary hard disk (Disk data transfer rate). In between came Memory (RAM) (Memory operations per second) with 5.9, Gaming Graphics (3D business and gaming graphics performance) with 6.2 and Processor (Calculations per second) with 7.1.

Although the graphics subsystem delivers relatively low WEI scores compared to those for processor and primary hard disk (SSD in this case), bear in mind that the relatively undemanding WEI tests will be hitting the integrated Intel HD Graphics 3000 rather than the discrete Nvidia NVS 4200M GPU, which will kick in under Optimus when the graphical going gets tougher. In two weeks of general 'knowledge worker' use, we found the T420s admirably responsive.

Lenovo claims "up to 10 hours" of laptop battery life for the ThinkPad T420s, when equipped with the primary 6-cell Li-ion battery and a second 3-cell Ultrabay battery. We didn't have the latter, which is a £57 (ex. VAT) option. To test the system's longevity with just the primary battery, we measured the system's average power consumption under idle and workload conditions, using a Voltcraft VC940 Plus multimeter. Dividing the resulting figures into the 6-cell battery's 44Wh capacity gives us estimates for battery life.

We tested the power consumption of the T420s under the Maximum Performance and Maximum Battery Life power plans, both idling at the Windows 7 desktop and performing a demanding workload (Cinebench 11.5's CPU test). Our battery life estimates ranged between 3 hours 19 minutes and 51 minutes, suggesting that Lenovo's battery life claims are optimistic and that you'll need that additional Ultrabay battery to get anything approaching a day's work from this notebook without a power socket to hand.

Conclusion

Much of the ThinkPad's design — and particularly the excellent keyboard — is traditional, but it packs plenty of up-to-date specs too: Core i7 CPU, hybrid discrete/integrated graphics, solid-state drive, USB 3.0 and a high-quality multimedia subsystem. All this makes for an expensive notebook, but it's one we're happy to recommend.

To bridge the digital divide, public sector telecom operator BSNL recently launched the extremely low cost tablet bundled with its connection. BSNL tablet, Penta IS701R, is manufactured by Noida based Pantel Technologies, is a Wifi model, and is priced at Rs 3,499.

The Mobile Indian got hold of BSNL's entry level model, Penta IS701R which comes with a bundled data plan of 5 GB for 60 days, after which consumers can recharge the same plan for Rs 750.

Here we bring the first impression of the device.

Specifications

Penta IS701R is a WiFi-only tablet with Android 2.3 operating system, a 1 GHz processor and 256 MB of RAM. Its 7 inch resistive touchscreen has 800 x 600 pixel resolution and a 16:9 aspect ratio.

Though the review piece which The Mobile Indian got didn't had HDMI port but the company officials said that the tablet which will be available in market will have an HDMI port through which it can be connected to a TV.

The tablet has a 3000 mAh battery and 2 GB internal memory that can be expanded through a micro SD card. It has a VGA front facing camera and a micro USB port that can be used to connect data card and to charge the device.

Look and feel

As compared to other low cost tablets in the market, Penta IS701R looks somewhat better in terms of specification but the foam factor or design looks similar to other tablets available in the market. It has a plastic body and a textured finish for better grip. The tablet has four physical buttons; three on the front panel - refresh, home and menu; and one on side panel for power on and off which doubles up as a screen lock button.

Penta IS701R has a VGA camera on the front panel which can be used for video conferencing, but the quality is average. For connecting the headset it has a 3.5 mm jack and expandable memory slot which can be expanded to 32 GB.

Performance

The device which The Mobile Indian got had an average response to touch. The response to swipe was frustrating as one had to press the finger harder to get the response.

Apart from this, Penta IS701R doesn't have a physical volume rocker button that means if you are using any app and want to control the audio you have to first go to the home screen and access the volume control icon, placed at the top right corner of the tablet. Also, for the short time that we charged the tablet, its back panel (under which the battery unit is placed) heated up a lot.

BSNL Tablet supports popular file formats like .doc, .docx, .pdf, .pptx, MP3, WMA and .RM.

We didn't face any issue while accessing the internet on Wifi mode or touch keyboard. As a matter of fact touch experience with keyboard was quite nice.

Conclusion

At Rs 3,499 Penta IS701R is a decent device for customers who are plunging into the world of tablets for the first time. There is nothing amazing about the device except the HDMI port.

With the OM-D, Olympus may have produced the range of digital cameras its users have been waiting for, but will the E-M5 model live up to the OM brand? Mat Gallagher looks at a prototype. The term 'reborn' is likely to be overused in forthcoming descriptions of Olympus's new OM-D compact system camera range. As with the introduction of the Pen digital, the OM-digital brand harks back to the classic 35mm film models and the original OM series, with elements of its styling included in the new model. The first OM-D model will be the E-M5 and Olympus has made it clear that, as with the Pen range, it is the first of many.

I suspect that Olympus users have pined for a digital version of its old OM cameras for a long time. They miss the simple design and compact body of the OM-1 and OM10. The E-M5, then, should get a warm response, as it looks similar to the OM-4. There is certainly a growing trend for classic styling, and Olympus must have been spurred on by the success Fujifilm is having with its retro-styled compacts, and forthcoming interchangeable-lens X-Pro1. Of course, there will be those left disappointed by the specifications of this new Olympus model, as it doesn't feature a full-frame sensor, but instead maintains the four thirds sizing and the 2x crop. Also, it doesn't use the traditional OM lens mount. The new digital camera has the micro four thirds mount used on the Pen cameras, but users will still have the option of the Olympus OM-to-micro-four-thirds adapter to attach old lenses for manual-focus control.

Features

On first look, the new camera seems really impressive. It is available in silver

and black finishes, with the silver being the most eye-catching, but both are pleasant to the touch and feel solid in the hand. The giveaway to the camera's digital identity is found on the back, as is often the case with these classic designs, due to the screen and menu functions. Unlike the Pen series, the E-M5 has a built-in electronic viewfinder. This has the same 1.44-million-dot resolution and 1.15x magnification as the VF-2 optional adapter for the Pen series, also featuring an eye sensor for activation and dioptre adjustment.

The image-stabilisation system remains sensor-based, as in previous four thirds and micro four thirds models, but now it has a five-axis adjustment. This means that as well as correction for the vertical and horizontal axis, it has rolling movement around all three (x, y, z) axes. According to Olympus, this extra movement allows the camera to avoid blur created by rolling body shake, which is not possible with regular stabilisation systems.

The E-M5 has a higher specification than the current Pen models. It uses a 16-million-pixel Live MOS four thirds sensor with 120fps readout for fast AF, and a new TruePic VI processor to provide ISO 25,600 capability and high dynamic range. This is likely to be the same sensor as used in Panasonic's Lumix DMC-G3 and GX1. The single AF speeds are claimed to be faster than a DSLR, or any other compact system camera model, including the Nikon 1 and

the Sony NEX. Presumably this is due, in part, to the full-time AF system. In continuous AF it is claimed the camcorder /  camera carries a burst speed of up to 4.2fps, while with single AF it will take 9fps. We will have to wait and

see how it handles low-light AF, as this has remained an issue for other similar contrast-detection systems.

Build

Like the Pen range, the E-M5 features Olympus's art filters and adds a new keyline mode to the existing array. One feature unique to the E-M5 is the ability to control the tonal range for highlight and shadow adjustments before you take an image, in much the same way as a fully customised art filter. The feature is controlled via the main control dial and a subdial on the top of the camera, with the results instantly viewable through the electronic viewfinder. This gives an added degree of control and avoids the need for any post-capture adjustment.

The magnesium body has been sealed to the same level as the E-5 DSLR, making it dustproof and splashproof when using a weatherproofed lens.

Measuring 121x89.6x41.9mm and weighing 373g, the E-M5 is smaller than the E-620 DSLR and OM-4Ti. The rear screen is a 3in OLED touch-panel unit, as featured on the Pen E-P3, but on a tilting bracket for vertical adjustment.

The standard kit lens for the E-M5 will be the existing 12-50mm f/3.5-6.3 optic but, like the Pen range, the new camera will look more at home with one of the short prime lenses, such as the 12mm or 45mm. Two further lenses, a 75mm f/1.8 and a 60mm f/2.8 macro, are under development. Additional accessories include an HLD-6 battery grip, an FL-600R hotshoe flashgun with a guide number of 50m @ ISO 100 and an LED video light.

With the broadening of the compact system camera market, the micro four thirds system used by both Panasonic and Olympus is proving to be a great compromise between size and quality. Although many people were hoping for an APS-C-sized sensor rather than the four thirds system, the four thirds mount is now well established with more than 25 compatible lenses and there are more in the pipeline from Olympus, Panasonic and Sigma. If this camera performs to the levels Olympus claims it can, and if this sensor is as good as that in the Panasonic Lumix DMC-GX1, the E-M5 could be the best compact system camera Olympus has produced to date.
