Hey I was planning on purchasing the new iPod touch. I was wondering whether I should get the 16 or 32 GB model. I have a decent amount of music and around 8 movies. Would I be okay with the 16 or should I spent 100 bucks more for double the memory? Also, would it be better to just buy the old model and get the 2.1 firmware, or just buy the 2nd generation touch?
