Xbox 360?

Wow, what an awful name. 360 means a complete circle, meaning right back where you started. How does that apply to the next-generation?

I personally liked Xbox Next or NeXtbox, or even Xenon. Xbox 360 reeks of Mountain Dew-type 'extremism' just for the hell of it.
 
I kinda like the 360 name. But does it mean it will be running dos as the operating system?
