Same here, wife and I have been running a pair of ASUS netbooks as primary machines for about two years now. Upgraded ram to 2G and drives to 500G. Mine replaced the laptop I bought in 2002, 12" Dell Latitude C400 which is still in use and running fine.
I couldn;t find the Linux model an cheaper than the windows model so I had to buy the windows model then install my preferred distro myself. I run the normal openoffice, firefox, thunderbird, digikam, etc.
wife dropped hers and busted the display and I found one on ebay for ~$30 and swapped it.
