We are back from travels in South America and were absolutely delighted with the mini-laptop. It connected flawlessly to wireless in all the various hotels (and ship) where we stayed, unlike our older PC, which tried to get back to our home network, no matter where we set up. And being under 2 lbs, it was a cinch to carry around. It also worked perfectly with Skype--one of the real pleasures of the trip was being able to call home from anywhere with crystal clear sound quality.
The lack of a CD ROM drive is occasionally a pain. For instance, I can't upload pictures and burn a CD, so we may eventually have to buy a CD burner--however, it has a Flash card port, so pix can be uploaded directly to, say, Kodak Gallery, without first loading them into the computer. Very convenient. I'm thinking of getting it out and setting it up at home (with fibre optic cable) in order to upload stuff while I work on one of the other computers.
So, size, convenience, and speed--what more could be asked for? Oh, it's free if you buy a cell/satellite mobile connection through AT&T, which requires a 2-yr contract. Otherwise, it's $350, which is what I paid for it at Office Depot.
