Microsoft apparently doesn’t spend money on research independantly, but rather asks the community. Microsoft wants to know what sucks, what needs to be improved, your ideas and dreams. Of course this all comes with the usual mumbo jumbo that they won’t use everyone’s idea and they won’t confirm that many of the ideas will even be looked at, if at all. And for once, you don’t have to signup (for a .NET passport or whatever) or give out your email (I can’t believe it) to actually submit your idea (first for MS!).
Anyway, all you have to do is comment on this blog post and your idea will become known to Microsoft (perhaps!). And maybe your idea will be added into Xbox Live. Who knows?
