Assuming you meant this to me? See my other comment about architectures. What you're describing sounds like Macintosh with PowerPC; was it ever an advantage? Maybe, but then it became a liability, and they switched. It hasn't exactly gone bad.

I'm sure there will be growing pains, but users will place such a high premium on systems that work together that it will have to happen at a software level even if there's differing technology under the hood.
