There's a mere 8GB of interior storage but you can increase it up to 32GB via the microSD card slot. The One X is also speedier than the 4S and its digicam is arguably just as very good, but its display screen is not as sharp and its storage just isn't quite as roomy. Sure, I'm hoping it'll be excellent, or at the very least good, but my interior baby -- who's been sulking in the closet at any time given that 1999 -- is dubious.
