Do you think it was worth upgrading? There is a thread from a month back where everyone is ranting and raving abuot how amazing the 2 is, but that was during the honeymoon phase. If some of the newness has worn off and you're now used to the weight change etc, do you regret the $500+ charge on your credit or debit card statement? Still worth it? Just curious. I held the new one at the Apple store, it's nice, but it seems like a progression, not a revolution.
