I surmise that once a new generation of consoles comes out and the older consoles are being used less and less for online play - we will see an increase in the amount of emulation for the 360 and PS3, but until then I think the original xbox is the way to go (again for the same reasons - it is older [cheaper] and has no official online support - so you have nothing to lose if you modify it. If you've got a good 360 or PS3, I'd hold onto it - I'm sure it will become useful someday
