What does it do?
As IBM snappily claims, the ThinkPad 240 is for those who want full functionality in a sub-notebook size.
What this means is that it is a portable PC that does everything your regular laptop does - but at half the size, with the same 'footprint' as a piece of A5 paper.
Despite these dinky dimensions IBM's ergonomic engineers have done well and the screen and keyboard are easy and pleasant to use; the only downside is that processor speeds are slightly slower than laptops. The 240 has been available for five months in the US, where it has been selling like hot cakes.
What's the competition?
There are numerous sub-notebooks and laptops available, but if you want something fully functional in this handy size, Sony's VAIO is the only direct competitor.
When can I get it?
It is out this month, priced at around £1,500.
