This is a device that suffers from a slow processor, low battery life and strong competition from the identically priced Fujitsu T1010 and HP tx2522. If you're interested in a portable device with good connectivity features then have a look — just don't expect brilliant performance.

The Fujitsu LifeBook T1010 is a good tablet notebook that doesn't do enough to truly shine. A middling performance from the hardware and a few small nagging issues such as noticeable lag when using the pen on the screen detract from a versatile and attractive device.

For users wanting more than just a notebook, this tablet-convertible PC is well-priced and does a very good job of recognising handwriting, whether cursive or printed. But its battery life is no good at all.

It runs Windows Vista, has a large hard drive and is basically a full-blown computer that's about twice the size of a smartphone. It's perfect for anyone who is after a small tablet PC for under $1800.

If you need a device that can take abuse and you're not afraid to pay for it, the Pioneer Dreambook Tough V10 combines adequate processing capabilities and connectivity options with a rugged design. The unit is let down, however, by usability issues such as an inadequate keyboard and the lack of ExpressCard slots.

The tiny Flybook V5 is aimed squarely at the business user. It's very mobile, has 3G capability and it can function as a tablet PC. However, it's a hard-to-use laptop and it's missing some useful tablet features, such as a dedicated button for rotating the screen.

If you're a road warrior looking for an excellent unit that has the right balance of power and portability while offering all the latest connectivity, and you have enough money, then the Toshiba Portege M700 (PPM70A-0G301G) is worth considering.

For mobile professionals who want to forget they're even carrying a tablet-convertible notebook, the P1620 is a valid candidate. It's not perfect, but it has enough features to be a useful office productivity tool while on the road.

For the travelling business professional, theT2010's 3.5G and tablet features, spill-resistant keyboard and overall build quality are strengths. It performs everyday applications and handwriting well, but it's has a few quirks.

It's not pretty, it's not powerful, but it will take a beating. If you work in a dusty or damp environment, or in an area where knocks and bumps are common place, then a notebook of this calibre is clearly a good option.

A very good Tablet PC that won't blow your budget, but will provide decent performance with great functionality and stylish looks.

This good-looking and portable unit has all the features of a great Ultra Mobile tablet PC, but nowhere near enough power to make it happen. With functionality issues like screen resolutions resetting every log-in and the touch screen disabling after intensive activities, the end result is a $1,699 toy for those who appreciate style and don't need power.
