If there is one influence the Xbox had on the gaming market that I don't like it is the controller. Mis-aligned analog sticks make no sense in a more FPS dominated gaming world. Triggers are not 'triggers' (gun triggers are either on or off, you don't press half way to make them fire slower). Racing games using these triggers as peddles meaning the right thumb is left doing nothing, let not forget their shame of a d-pad.
That said without them we probably wouldn't have online gaming in all it's glory today either (... like having to pay for it).
Hmm, pie.
