I finished a new version tonight. It works great on the nook with gingerbread now. Gingerbread enables bluetooth on the nook color which makes me question why the device did not originally enable the bluetooth chip that was obviously inside. I was able to pair it with my apple bluetooth keyboard the way I do with my ipad. The ipad is pretty great but the nook is so much more portable. Its large enough to have a lot of screen space but small enough to be jammed in some big coat or jeans pockets. I only wish it had its own 3g chip the way that the ipad does although I guess tethering with the phone is actually a better deal because it does not require an extra account or monthly fee.
Here is what it looks like on the nice big nook screen.
Version 1.23 had a bug that forced the app to quit on reload. If you are having issues make sure you are on 1.24. Check the market and see if there is an update. If so update it.
The combo rocks.
