I have a Nook tablet with 8Gb internal storage and a 32 Gb MicroSD card installed. Almost all of the Google and Nook apps cannot be moved to the MicroSD card space. Android takes up almost half of the 8Gb internal storage and the unmovable apps take up almost half of the rest, leaving very little space to work with. I've had lots of occasions where the system has told me it needs more space to do an update, and I would have to delete some of my apps to get that update.

I really like my Nook, but having Android and Google apps locking up so much of the internal space seriously impacts its usability.
