Hi guys, I bought a 1G 32gb touch in august, and the store has a 90-day return policy, which is incredibly friggin' awesome. So now with the release of 2G touch, are there any compelling reasons to switch - or not to? I like the speaker, but the hardware changes inside is what really concerns me. Is there considerable, i.e. appreciable differences in performance? If performance is same or better, I'll get the 2G. I want the speaker. If not, I'll keep mine... any advice?
