I have a Kindle 3G. LOVE IT!!! Nothing like reading in bed at 1:00 am, finishing your book, being mad the author left it on a cliff hanger, going to kindle store and downloading the next book to see if everyone is ok, all within 90 seconds! I love my Kindle and when I look for a new purse I take my Kindle along just to make sure it will fit in new purse. Kindle offers book deal of the day, and you can get some great titles for cheap. I haven't done any library books through Kindle yet, but I must say the 3G is awesome. 3G allows you to buy books wherever, as long as you have a cell phone signal...
