Hey Jason, Thanks for the tips. I've posted my note on the Android Developers list so hopefully someone over there has already gone down this road.
As for the emulator tip, I've found some images and will be installing them shortly. Sometimes I kind of forget what I'm working with and just assume I've only got the device! So yeah, after upgrading to the new Cupcake on the emulator... meh I'd say no improvement :-(.
