i had one of the early 'netbooks', a 10in model. slightly shrunken keyboard to fit the form factor. it sucked for typing.
probably better off with a tablet and one of those cases with integrated stand and bluetooth keyboard. and you wouldn't need a bottom-of-the-barrel model, either, to keep with a $300 price point for everything.
every. damn. day. the worst might be i get to the outer door at the office, ready to go outside. and i just stop. 30 seconds later, shake my head a bit and go 'oh yea. i'm leaving now'.
