No experience; but still a piece of advice you may want to take into account:
Keyboards probably aren't the problem if your hands aren't too big, however screen real-estate *is*. You'll notice with websites that many of the more `large amounts of text' types do seem to be based around the idea of a _minimum_ of 1024*768. Unless you plug in an external (USB) mouse which has rather good low-friction scrolling (as opposed to the incremental model of nearly all mice) that may be a bit annoying with N-page documents (with N any amount larger than 2).
It's not just that your screen is particularly small. It is also that unless you get yourself an OS tuned to a netbook (if I were you and I were to get a netbook anytime soon, I'd most definitely try out Moblin for that: if only for the fact that its a heavily optimised Linux for the Intel netbooks: 5seconds for a cold boot to desktop is not bad at all) you will notice that all aplications love to take up some X amount of vertical and screen-real estate, with X likely being about 50px for anything that supports tabs, and in the vicinity of ~100-150px for things that use the 'ribbon' thing or uses many layers of toolbars (so that is many common office applications right there).
I find myself noticing that on a 1280x800 laptop screen: I have my desktop configured to trays, task bars etc... If you want to do anything like displaying 2 Word documents side by side, it's going to be mildly unpleasant I'd expect. It takes a fair amount of re-sizing already on what is a much more convenient resolution of 1280px in width.
