A friend of mine lend me a tablet (from Barnes & Noble), and I wanted to try it out, but with some more "open"version of Android.
In order to install it, I've found in the xda-developers forum a great post about how to download and install Android into this tablet. I've tried out and it worked great!.
Right now I'm trying it, specially for books reading. To start, I've installed Moon+Reader. I will write some reviews after a while, to see my experience with this reader.
The tutorial could be read here (great job!)

The only thing I have to add, is that after copying the image to the sd card by using the "dd command", then a "Backup"partition is created with 130 MB of size. At the beginning I didn't understand this, but then I just copied the CM7 image file into this partition and booted into the nook device. After this, the new version of Android (CM7) started to install.
More info about these to come (I hope!!).
