The Xscale processor is an enhancement of the ARM processor. Instead of running at 200 mhz, it runs at 400 mhz, among other improvements. There are some ups and downs to it. Current ARM software runs on Xscale platforms, but some applications lack the speed enhancements it is supposed to provide because of inadequate optimazations (sometimes runs slower than on ARM ppcs) I have only heard of video and 3D programs that have this problem
Some of the pluses are increased battery life. Instead of a cromulent 2-6 hours on ARM ppcs and lower, Xscale devices can be used from 8-12 hours without recharging. And many other programs get the speed enhancements it should. The OS and many 2D games run twice as fast as it would run on the ARM, like it is supposed to.
If you are thinking about buying an Xscale, wait a couple months for the problems to be worked out. There are a couple topics regarding the forementioned problem, which could provide you with further info.
