Help! I'd like to get one of these for my sister for her birthday. I was in Target earlier comparing Kindle vs Nook when the sales guy suggested iPod Touch, which has both Amazon and B&N Apps. And also is currently on sale. Does anyone have any experiences, ideas, etc. to help me decide? Also, are any of these capable of sending and receiving text messages? Or are there other similar tables (around the same price range) that I should consider?
