"How does this compare to the 7" Galaxy Tab 3?"
I had purchased a Tab 2 7in, on sale, just after the Tab 3 came out. Had some trouble with the unit (it was a discounted display), so I paid difference, and tried the Tab 3. It would NOT move load nonsystem apps to MicroSD. Tried apps, et. al. I finally talked to an engineer at Samsung, USA. He stated that the 7 in Tab 3 was NOT designed to allow apps to load on the MicroSD! And as an 8 GB mem tablet, a serious design flaw (by choice!). So, I returned it, and went back to the 7 in Tab 2, 8GB mem with 32 Gb MicroSD. Happy with it. Though I believe, that all tablets, MicroSD or not, should have at least 16 Gb mem. The Nexus, with no icroSD but with 32 Gb mem, should be plenty. Though I might look at the ASUS MeMO, 16 Gb 7 in for my next ... However, this is a good deal with 32 Gb mem.
