Okay, so I'm looking at Nooks and Kindles and what not (not necessarily going to buy one because I really like the concept of reading an actual book), but I can see they do have some advantages. One thing I can't seem to figure out from the reviews - how does it work? Do you have to subscribe to some internet service after you buy the device? If not, and you don't have wi fi, how do you get your books? If I do decide to fork over some cash to buy one of these, I really don't want to have to then subscribe to an internet or wi fi service so I can use it.
