The netbooks have gotten so cheap - maybe you're allowed a netbook and not a computer.

Last christmas, I replaced my laptop (8 lb behmouth from 2001 that mostly worked fine, pieces of plastic case falling off) with a little dell mini netbook... and seriously, I've only booted the laptop up a couple times in the last year... because the mini is more than enough for what I need and sooo light in comparison. I do have a nice desktop though...
