My folks got us an MSi Wind netbook. My wife loves it. It's tiny (and so is she) so she's excited about it on that level (as well as on many others). We haven't done much with it yet except check email and play Soltaire.
The only problem, visible for now while answering emails, is that the cursor sometimes relocates at random. It's like what sometimes happens in ytalk (at least to me). I haven't found a solution yet.
