I'd love more storage too, but IMO, that's more a cost/marketing restriction at this time rather than a technical hurdle, that's why I didn't mention it.

I'd actually prefer skipping 64GB and going directly to 128GB at a minimum. My locally stored copy of WIkipedia alone takes up close to 6GB without images. Space goes quickly when you start to add apps/games that eat anywhere from 500MB to 1GB. Then movies take up a lot of space, in the end not leaving a tremendous amount of room for music.
