I would have liked to see it but even if it came out at 64 GB I'm not entirely sure that I would have bought it over the 32 GB version, although I'd be considering it. That extra memory can help create a buffer where I wouldn't have to worry about running out of memory, I like carrying everything with me (music, videos, photos, apps, etc.) and right now that would amount to about 20-25 GB or so for me, and over my 2 years on the phone I'd almost be sure to hit the limit.
Thankfully I'm holding out at least another year (or two) hoping for a Verizon version and by then prices will come down on flash memory.
