Apple should never have given $100 to iPhone moaners. Look what its done.
I agree, but the original poster was not in this situation.
True, he knows enough to post here and probably should have seen the update coming but the vast majority of people out there don't pay attention to technology. They get up in the morning and decide "I want an iPod today" and go make their purchase.
That being said when the new ones come out in a few days they either return their purchase to get the updated one, or live with the mistake. I've gone and done price matching on DVDs and other tech when I've seen it go on sale withing a week of purchasing it. How is this different?
The OP may have to suck up a restocking fee if he wants the updated capacity, or there may be a price match as stores reduce the price on the 30 GB to empty their remaining stock. Apple is known for keeping product updates and features secret, and although the internet is always ripe with speculation, it is wrong as often as it is right.
The iPhone situation was different since many receiving the compensation are outside of the well established 14-day return window and should be getting nothing, no matter how PO'd they are. But Apple bent to the pressure and in their view the $100 store credit is cheaper than the bad publicity. It's Apple's decision, not mine.
