Well, they don't make computers this small. The keyboard is typeable with medium-large hands; I'm typing on one now. It's way lighter than the competition. I has an awesome screen (1600 resolution horizontal). Yes, you can scale text on most web pages, so small is *good*. We mostly use it as a travel computer, but for that, it really can't be beaten.
The linux support for this isn't quite there out of the box (at least for the graphics driver) but it is available, and recently has gotten pretty snappy. Red Hat/Fedora may have better integrated support for this notebook than Ubuntu. For ubuntu, you have to add a foreign repository and add in the drivers and build a kernel module for the driver, but it's not hard; there is a long thread about it on the Ubuntu forums.
