As someone who has been WAITING for B&N to get off the dime and come out with their new software, and decided that I didn't want to risk core rooting, this is the solution I've tried and I like it. Lets see $800 for a Xoom, no thanks....
I have dual boot on a 8gb SD card, class 6, not a great solution, but when B&N comes out with their new software I can boot up the B&N sofware directly and let it update. Who knows, they may come out with something great.
My biggest hassle was getting the Android Market loaded on the card and functioning... finally had to have a co-worker do it for me. Quite frankly it just turned into a circus trying to do it myself.. download this, download that, side load XYZ... type in some greek to put it on the card; jeez, I can browse to it using Froyo but I can use it? How silly is that?
If anyone knows an unconvulted way to load Android Market I would appreciate you linking it as I'm sure MANY people would.
