i actually work for a company that buys all the acer, gateway and emachine RMA's and refurbs them so i've had a lot of hands on with the little aspire ones and i can tell you that they are a very nice little laptop. There are two kinds the ones with linpus (acers slimmed down linux) and ones with XP. the main diff is that the linux ones come with an 8gig ssd drive while the winxp ones come with a 130 gig laptop hdd. BUT they both have two sdhc card slots, one to expand the hdd and one for media cards and whatnot. I am porbably going the linux route and throwing in a large sdhc card. they are very light. i can't believe that they are 7 pounds. also, they both have a built in 512 of memory and a slot for extra. so you could just get the linux one and throw in more memory for less money....
