I still don't want to read books on it but I'm thinking this might be a cool tablet. I have a Dell Streak and it's okay but I don't LOVE it. Me and Android just don't click. (Yes, I know Kindle is 'Droid, but the OS seems to run better on this device. My main problem is with the battery life of the Streak.)
I use my tablet for reading periodicals, news sites, checking weather, Facebook, Twitter, and sometimes for blogging. I don't read books on it and I don't play games on it.
The Kindle Fire is definitely cheaper than an iPad. It could be ME.
