Surprisingly the Nook Color works fairly well. You don't have to jailbreak the Nook just flash an SD card with Nook Froyo 0.6.8 and your done. Keeps the Nook under warranty but it's Android 2.2 I believe.
It works well for what I use it for, web surfing and e-mail.
Very interesting... Never considered one of these as they are not officially sold in Canada. Once can find them on Kijiji and craigslist for 250-300 bucks new/barely used.
I am reading about this SD card root mod to make it run 2.3, but apparently it can also run Honeycomb?
