I had the mogul, and switched to the touch mainly because of the size, I do too much outdoor activity to have a one pound brick bouncing around in my shorts, it's dangerous. The touch's speaker is a lot louder, but I truely miss my mogul, it was like having a sweet tablet pc in my hands, plus the GPS and rev.A is already available for the mogul and the WM 6.1 will be available soon.
