Great app!!!  It works flawlessly

I've got the 8GB version coming but I wonder if I should have gone for the 16GB... My thinking was thus: I don't plan on storing a lot of movies or space-hogging content on board, just mostly surfing, listening to music, etc. so I'm hoping that I won't need all that much mem.  This will be my first tablet so I don't really know how I'll be using it on a daily basis.  If money were no object then maybe I would have gone for Galaxy or one of the high-end, expensive models.  But price did enter into my decision to go with the Nexus.  Am I just fooling myself?

Based on usage so far, even 16 Gb is not enough.  I wish that it had expandable storage for up to 64Gb.  I bet hat future version would have it.  As long as you remove movies and shows that you have watched, there is not much of problem, however.
