If this MacRumors post is to be believed, full Calendar editing will soon be possible on the iPod touch, with Steve himself labeling the lack of editing as “a bug that will be fixed in a future software update.”

I’ve always wanted this feature and sent feedback to Apple about it. The touch would fit my needs well: a device to manage events, play music, and do light browsing over campus Wi-Fi. I think contacts make more sense on an actual phone.
