It is not hosed. I am able to access the device on ADB so it would be possible to flash the factory firmware back and reboot.
It is just a process that is hanging up. Did you modify anything before closing it? install any apps?
I think it might be because I replaced a few files from the nc_gapps.zip that they used on the NookColor (that is using Android 2.1 based on Linux kernel 2.6.29) and we are using 2.0. Replacing Libs is not a good idea.
But hey...that is how you learn.
