While I know people* love their Kindles, I'm intrigued by B&N's Nook. The Nook and the Kindle both have the same kind of display, display size, adjustable text size, etc.
What Nook has that Kindle doesn't is what makes me want a Nook instead of a Kindle (not that I'll get either any time soon because I just can't afford it)... Nook has Wi-fi, including free Wi-fi in B&N stores. It also has a new beta software pack to allow some web surfing.
Nook has a microSD slot, too, for more memory. B&N offers more ebooks in Nook's format than Amazon does in Kindle's, more than a million titles, so the memory expansion might actually be needed. Five hundred thousand of those titles are free, and you can read any ebook free while sitting in a B&N store... Up to an hour of reading time without buying the book per day.
Nook also offers the ability to lend your ebooks without lending your device, sharing the book between blackberries, pc's, and Apple devices. I think there's an imposed time limit, two weeks, IIRC, but still.
Hardware wise, Nook has a color touch screen below the reading screen for browsing your books, and you can browse your library by cover art through this screen. It also has a replaceable battery, which I like.
If I had a spare three hundred bucks laying around I'd buy the Nook. Unfortunately, I don't, so I'll just sit here and sigh at it, unless some generous reader wants to show their appreciation......
Anyone? Anyone? ....... Yeah, I didn't think so, but it was worth a shot.
*I'm looking at you, Alan and yes this post is mostly to make fun of you. Deal with it.
