Xbox 360 is just a less durable Sega Dreamcast.
Its cash-cow is one game, exactly like Dreamcast's Sonic...Halo is Xbox's money-maker and besides that, there isn't a game worth buying for the 360...at least not any already available to other consoles. This wouldn't be such a huge issue for me if the 2 consoles I owned didn't red ring. I gave up after the second. It's a defective system being mass-produced, re-polished, and re-sold over-and-over again. Very similar to Ford in that sense.
Back on topic, Halo IS the ONLY reason xbox ever became as popular as it did, Master Chief is Microsoft's Mario...who's now way past his "point-of-coolness" date and Microsoft needs to find their Link.
