The 360 controller is by far the best controller to have ever been made for a console. <=PERIOD
The dual shock is a horrible design, especially with the clear afterthought of the analog stick placement.
They could have at least swapped the d-pad with the left analg stick, so that it would be a little more comfortable with current gaming, but oh well. It is at least better than that boomerang design.
As for the tilt thing...
woooooopty friggin dooo
I suppose it could be neat, but it has been done before, and like the analog sticks on the dual shock, seems like an afterthought to (as already mentioned) steal some of Wii(tarded)'s thunder.
I'd much rather have the rumble they they took out.

As for the price...
I'm not looking for a Blue-Ray player to begin with, and though its addition is a factor in that cost, and when compared to those stand alone players, it is indeed a value, I am interested in a gaming console. As far as that goes, the price is insane.
