@spivonious:I haven't yet played any games nor have I used a kinect on it, so you are on your own with that. For the life of me, I can't figure out what the bigger hard drive is for, but I suspect gaming is the reason.
I've been able to use an older you-tube addon that was installed on the MCE to browse for and watch videos, but the xbox has a much better you-tube app so there was no reason to keep using it. My MCE has a ceton 4 channel HD cable card adapter that has some addon softare for the MCE that also shows up in the xbox extender UI, but it's really just configuration for the hardware.
