No need for such negative comments. If you're not interested in this new iPod touch, then that's perfectly fine. Plenty of people are and I've heard many of them are happy with their purchase. The $199 price point is important, as Apple has previously stated in one of their keynotes. For the moment, they couldn't have reached that price point with a 4.7" screen or Touch-ID.
Yes, I agree that many times Apple holds back on features on purpose so that they can include them in the next versions of their devices. But nobody can deny that it makes sense in terms of their product strategy and business.
