If I'm shopping for an PMP then I don't care about anything other than the features that facilitate its use as a PMP. Its like when someone tells me their phone's camera is better than mine. That may be true...but it doesn't matter to me since I'd just as soon have no camera.
Same with most of those features. If you REALLY need mobile email or web connectivity you won't be using a Touch with only a wifi connection. You'll have a phone that does keep you connected. That makes those features superfluous at best. And if you don't need the features enough to have a data enabled phone...I seriously doubt most of those people would choose to hunt down a wifi hotspot just to get their email on the go.
You present the Touch as basically not an MP3 player. I don't think that's how Apple markets it.
