ok...i'm just starting to look at e-readers. don't know much yet...i have learned you can download e-books and read them on your computer or get them for a kindle or nook. some books can be "borrowed" from your library, using adobe digital editions software on your computer and copying to your nook. kindle is not quite "there" yet (i think you need something called "overdrive" to support the kindle and, at least in my library system, that's not yet available). some devices get books directly through a wi-fi connection, requiring you to be near your wireless network or at a hotspot (starbucks, barnes and noble, etc.), while others use wi-fi and 3G (i heard kindle makes you pay a fee for the 3G connection, though i think that may no longer be the case).
within each brand, there are a variety of options...most nooks use their internet connection mostly for downloading books (and some light google searching and e-mailing, I think), while nook also has the "color" which has more robust internet functionality - but with the "color" you can only connect thru wi-fi...this means that with the lesser priced nook you can only buy books "anywhere" with the 3G connection; with the "color" you can do real web surfing, but only in a hotspot - so if you're stuck in a cornfield, forest, etc. you can't surf and you can't even get books.
...decisions; decisions.
just wondering what others are doing for e-reading. also, feel free to correct any of my "facts" - i think some of what i've read is outdated.
thanks eveyone!!
