Beware of sample bias: People who have netbooks may be universally happy with them, but you're not hearing from the population who found the keyboards too small to type on comfortably (even for short-haul typing such as emails) and opted for something with a full-sized keyboard. Jeff found a model with a full-sized keyboard, but those are very recent. Stores in my area don't stock them yet.
It's not really sample bias; had those people returned their netbooks or complained bitterly how small they are, then I'd have posted an entirely different comment.
I didn't even want a netbook, it was given to me as a gift from someone looking specifically to get me a completely superfluous technology item. I didn't think I'd use it since I have a really nice laptop. I have no complaints with the keyboard -- it's the lack of vertical pixels that is annoying.
