I've tweaked the screensaver to a MoDaCo logo (had to be done) and started playing around with what's installed.
I have the nook button going to normal home for now and a long press loading relaunch. I'd like relaunch to load at the app view though ideally.
I'm probably going to lose a bunch of the apps that got installed, Music, Calendar, Gmail, Talk etc... I have a phone for those. There's a few where i'm not sure whether they do anything useful yet (Contacts, Gallery, Library, Nook friends, TestCenterService, NookHWTest, DeviceRegistrator, Social)... not sure what i'll do with those.
All i've really installed so far is Amazon Kindle, straight from the Play Store, which works OK, but the page animations are a bit annoying.
I've used the touch mod mapper to map bottom left key to back and bottom right key to menu. Interestingly, if we can map the top buttons to dpad left / right they would work as page turn buttons in Kindle!
Lots to explore still...
