$400? $100 for 16GB of memory? Geez? I guess that means the 64GB, if it's ever out for Sprint, will be $500-600 SUBSIDIZED! Or, what, like $1,100 contract free?
Question is, who needs that kind of storage? If you can pay $50 or so for a 64GB SDXC card and put all your video, audio, and photos on that, wouldn't that suffice? Even without rooting, 16GB should let you store multiple hundreds of apps along with their data in the phone's storage. I just can't see using all, or even half that space right now. At least not with the current app sizes. Maybe if something happens and we start seeing apps that are typically 200-500MB a pop, but currenlty I rarely see anything above, say 15MB? And most are well under 10MB, or even 5MB...
