Purchased both Apple refurbs for $350/64gb wifi and $400/32gb cellular, will keep one and sell/return the other. Which one should I keep? Or should I get something else (< $400)? The mini will be mostly used for school - logging into school's website and viewing/storing PDFs (biggest PDF is close to 800mb). I'm tired of lugging/pulling out my MBA for such minor tasks. My phones (OnePlus 64gb and Nexus 5 32gb) tell me that 32gb should be more than sufficient, especially since I won't be taking pix/vids w/ the mini. But I read that HD apps are taking up a lot of space, and I hate it when my MBA runs out of space. In terms of connectivity, I have school wifi, 5gb phone tethering, and a 30gb hotspot. I'm leaning towards the 32gb cellular for GPS and convenience, but the 64gb seems to offer a better value!
