i've not used one myself but from what i've seen and reviews etc theyre pretty good little bits of kit, as long as you see them as internet on the go then you'll be happy with one, as alot of people try to compare them with laptops and moan about the screen size being to small for films (wtf! why would u want to watch a film on one) as well as the specs not being great (900mhz celron cpu)

the only niggle i've herd from them is due to the small screen size on alot of websites u have to scroll left to right etc, but again small price for mobile net.
