Apple hit it on the head: The iPod touch is for people who don't want to drop their current mobile phone (or don't want one at all), but love the other features the iPhone has. I'm in this group. I'm happy with t-mobile and don't want to pay more for AT&T and their slow-as-cold-tar Edge network.
I've never really cared about video-to-go in such a small format, so the new nano doesn't really affect my thinking. I'm perfectly happy with my 2nd gen nano. If I want to watch video that badly (on a trip, for example) I'll bring my laptop. But that's just me.
Too bad about the price drop for you early adopters, but that's the way the revolving tech door works. Several times I've purchased a Mac and the newest model was introduced a month later. That's life.
