I honestly hope that a touch iMac isn't in the pipelines for any time soon. I have a 27" mid '10, and the thought of having to point and tap for everything seems like a nightmare. While OS X might be able to be modified to be simpler and better suited for touch, think about all the 3rd party programs. I can't even begin to imagine Adobe Creative Suite with touch, you would be restricted to browsers (I use Firefox, always have, always will). There is a very very long list of things that would need to change for it to work. In small devices like the iPad, which imo is about as big as you should go with touch, and phones, touch works well. Any higher than 10" and it becomes more work. I will be sticking with the biggest iMac that is available at the time, and whether that is 27" or 30" hopefully again, the thought of using a screen that size for touch is horrible. The mouse works perfectly well, though I use my trackpad 99% of the time. The trackpad probably isn't ideal for most people, but I like the fact that I can get from one edge of the screen to the other just by moving my wrist, and all the multi-touch abilities that comes with it.
