well, I won't be getting one of these anytime soon, but...
When the 32GB comes in under $20, and with current trends that's possible in 2-3 years, maybe a year more and the 64 will be under $20, and assuming they allow non-FAT file systems, I won't need BlueRay Media ever again...
BR blanks are still averaging $7-10, and won't be under $3 a disk anytime soon, and are write once. With a 32 or 64GB Stick, I can carry several 1080P movies around, change them up whenever I want, share them with friends, and never worry about scratching disks (or slow burn speeds).
