Query: Nice

This is my first e-book reader, and I really enjoy it. I did a lot of research and comparisons before I purchased, and this seemed to be the right one for me. I would have to say; the most convenient feature is the ability to wireless download a book from anywhere (Whispernet). I love the fact that I do not have to sync to a pc or be at a wireless hotspot, it just works from anywhere, and it's extremely easy to use, that's what sold me on the kindle. I know this technology is still in its infancy, and has a lot of room for improvement, which will come with time, and new hardware/software releases, but it's a great way to store and read books, magazines, and news and save the planet at the same time. It is the future, and soon all of our reading material will be delivered in this or a similar format. I gave 4 stars, because like I said, it's early and will only get better, but in my opinion this is probably the best e-book reader you can buy right now.
