From what I understand (I'm no expert) is it runs on the original Atari 2600 hardware using PlusCart, it's not just using it as a throughput for the display.

Xbox360 might not be the most important console out of ALL consoles, but I think it's the most important _modern_ console. Online gaming, online store, an indie game channel with XNA (which itself was revolutionary, even though some of its importance might be forgotten today), HD support. A lot of things it got right back when these were all brand new on a console. Plus it had geometry wars.
