Yeah, I also found it uncomfortable to move via the accelerometers. Maybe it's possible to get used to it, but intuitively I would have thought the other way around (as ivgalvez suggests) would be better. But then again I don't know how accurate aiming would be with accelerometer.

Oh, and the good thing about getting the DDP device is that it's practically the only way to get a non-localized version! So I have the four arrow keys.
