1. how difficult would it be and will there be like "ms word" emulated with xna. and a webbrowser?
cus i can sell my pc if i could have those two.
2. is ms have any say in what games we put in our 360, cus i wanna have emulators.

if my questions seem stupid, sorry

I think that MS will probably have a say in what can be released for the XBOX 360 XNA Kit. I mean, I don't think that MS will allow emulators espically since these are in a grey area. But a person could code an emulator written in XNA & distrubute the source code & any who wants it just has to buy into the XNA creator's club & compile the emu for your 360.
