iOS 9.3 is coming in the Spring and will introduce Night Shift as well as a number of other new features.
iPod Touch Calendar to Get Add/Edit Functionality?
Steve Jobs reportedly replied and addressed the last two issues:
Nothing can be done about the games. The new iPod touch is a completely different animal inside than the old iPods and the games just don't translate. The inability to edit and add calendar events is a bug that will be fixed in a future software update.
The lack of calendar input received a lot of attention when the iPod touch began shipping, as this feature was originally described on Apple's iPod touch feature list, but subsequently removed. According to the email response, this oversight is described as a "bug" and should be addressed in a future software update.
Though rare, Steve Jobs has been known to occasionally respond to emails addressed to him.
