Interested in purchasing one but not entirely sure whether they are worth it?
If you want a decent ebook reader, they are quite nice. The new color models will also do video streaming from the internet as well (over a wifi connection). In any case, they are Android (Linux) tablets essentially, with Amazon's ebook reader software and other proprietary tools. Myself, I use a Kobo book reader. It's uses a black and white e-ink display (very low power), so it will go for days/weeks on a battery charge. No video playback, and their web browser is awful, but for ebooks it works great and handles just about all ebook formats known. They also have a bookstore where you can purchase and download ebooks from, much like Amazon. You can check out their web site for more information: http://www.kobobooks.com/
Ah thanks, i'll take a look, it sounds good!
