I do use one for work stuff

But I might be an exception...

I do have an EEEPC 900, which has plenty of screen space as compared to the 901 (for the same screen size... go figure) and is very nice for basic things such as office work (text, spreadsheets, presentations), email, skype and whatnot, but also moderate image processing duties.This suits my needs quite well while being much less cumbersome than my 15" laptop.

On the other hand, the Windows version feels really cramped and makes any kind of work a painful experience, you'd have to get a 11" screen to get an acceptable "experience" for anything else than e-mail. And at this size, you will probably go for a real laptop instead, while getting a smartphone for email.

As far as I can see, when running Windows the small netbooks offer barely more functionality than smartphones -except for the storage space, but that's not what SMBs get a netbook for- while being considerably larger and having a pityful battery life. MS kinda managed to kill the netbook market. For now. It will be interesting to see what happens with the latest Sony.
