Acer's TravelMate C312XMi is a great device if you're after a notebook first and tablet PC second. The relatively low screen resolution impedes its handwriting recognition.

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.

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.
