I'm buying one this afternoon, for Sprint. Due to walmart/Sams' sale, this is the dilemma I'm faced with. I can get both in Space Grey like I want. It doesn't seem like Sams/Walmart even has, let alone is discounting, the 64GB plus. Normally I was all for the 64GB. On my HTC One, I was using 7.5GB in apps, about a gig of music, a gig of various downloads and 3.5gbs of camera photos/videos. I could cut out the gig of music and could frequently cloud/PC backup my photos. In other words - I could probably manage with 16GB although it would be troublesome, while 64GB would be an excess in which I'd never have to worry. Which would you take in this scenario?
