Sure. I think Intel's RDRAND, using thermal noise (or whatever) makes more sense, because you don't have to hook up some antenna -- I'm no physicist but my guess is it gets substantively affected by atmospheric noise.
Because pseudo random is good for most purposes, and there is enough chaos in the machine to seed cryptographic random numbers. So why add extra manufacturing cost.
My point is, if that is true, then wifi and bluetooth would have those same negative implications regardless of what you are using them for.
