I have my very lightly used B&N Nook Color for sale. It has been rooted and is running CyanogenMod 7 (stable release); which is one of the most popular and proven AOSP Android 2.3 (Gingerbread) ROMs. CM7's native tablet tweaks replicate some of the features of Honeycomb which make Android more useful on a tablet.
The device is capable of installing apps from the Android Market; Google Apps are present and work great. Android Nook and Kindle software work great for the intended function of the device (reading e-books).
Box, charger, and 2GB MicroSD card are included. The MicroSD card is for booting into ClockworkMod Recovery for flashing/backups/etc. A secondary MicroSD card is recommended for day-to-day usage but is not included. Also included is the B&N Industriell Cover (link below).
Great out-of-the-box Android tablet experience at a lower cost and no contract that many of the tablets on the market have.
