I didn't take Wellersl's suggestion and test all the ROMs out there to see how they'd work for my Nook HD+. That would sort of defeat the whole concept of a fourum, and seems like a task more suited to a blog. Still, I did install a CM11 nightly, twice now. The first install worked great for a few days, then I installed a new theme and it started to crash and reboot constantly. So I wiped it and reinstalled the most current nightly. It is working, but I've had a few instances where Chrome crashed and it rebooted, but these have been fairly rare. So I'm going to stick with this ROM and see how it goes. My biggest complaint is the lagginess of the back button (soft button) and N button (hard button) when trying to get out of and app. Also trebuchet launcher crashes every now and then. Thanks to leapinlar for his excellent dummies guides to CM 10 and 11. And thanks to kokercy for his suggestion to not install flash or java on browsers which seems to make them more stable.
