Kindle Fire is dope. Great spec, great software, killer price.
But it's basically just my NookColor with a faster processor, so don't need it. I have all the Amazon apps on the NC, I use Kindle for Android as my e-reader... and cos I'm running Gingerbread I have all the other options, plus Android Market etc.
I know a few people that are interested though, and it'll almost certainly sell a shitload. I know a few people that are looking into getting one.
