I think halo is a good smart marketing move to associate future Microsoft consumer products with halo. The 360 is by far microsoft's biggest consumer electronic success, and halo it's flagship franchise. Kids growing up now with the 360 will know it, and it's not associated with the boring windows enterprise stuff. And if you don't know halo, the names sound okay anyways.

I think they should stick with it as well.
