Personally I had a Sony Reader when they first came out and enjoyed it a lot, though the Connect website left a lot to be desired. Now I have an iPad which I love for reading in dark rooms with the backlight, and for it's capability to access multiple source websites for books - iBooks, Kindle, Nook. I don't know if I would recommend an iPad if all you want is the ebook functionality - there are a lot of good options that provide that, but personally I love it for books and games, movies, and everything else.
