No comments yet, just wanted to let you know that you're not talking to yourself...
I'm only vaguely familiar with PSoCs and Atmels, though, and being already a bit overwhelmed by trying to force-feed my brain with the likes of ColdFire and Cortex M3, I'm a bit gun-shy about the prospect of trying to make sense out of other architectures at this time.
So I may end up just sitting on the sidelines watching but without a whole lot to contribute...
