sony e-reader and the like ??

anybody got one ? sister wants one for the 2nd year running (put her off last year).i think they're a good invention if you use on the move and you're away from home a lot, but she's not and i can't see the point in having one if you're gonna pay almost the same to download a book rather than have it to hold in a physical sense.

i would only consider buying one of these if i could download best sellers from net and i've had a quick look on torrent sites and can't really see any, unless i'm looking in the wrong places....any advice greatly recieved :)
