My biggest gripe with the Kindle Fire is it's wifi only. When they come out with a Kindle that lets me download books and surf the internet, all while using 3G, then we'll talk.
In the meantime, I'll download the Kindle app, and the Nook app, for my netbook computer. Yeah, it's a little larger than a tablet, and it's not as nice to read on as a kindle using E-ink, but it will do so much more. I do wish it were touchscreen though!
