Here's hoping that they at least double the RAM in the refreshed iPod Touch to 512MB like the iPhone 4, even if they stick with the Apple A4.
Presumably with the elimination of the iPod Shuffle, the price of the iPod Nano would move down and make room for cheaper iPod Touches.
It would be nice if Apple no longer offers 8GB models of the iPhone and iPod Touch and bumps things to 16GB for a minimum. With the size of apps ever increasing, some games for instance being ~1GB when installed, 8GB is very limiting considering you still need room for music, video, along with some room whatever photos and 720p video you take with the cameras.
I like the idea of killing off the 8gb line and making 16gb the minimum. After the ~900mb or so that iOS takes up leaving you with ~7gb for your content, there just isn't enough space for all of your content without having the constant feeling of sacrificing content in order to have space for other things; the constant managing it takes to make sure you can fit what you want when you want on the device is dreadful.
