I said I can see Apple doing it; reinventing entire markets to suit itself is something they've gotten rather good at. I didn't say it was desirable for the rest of the industry to sit on their behinds while Apple eats all their lunches.
Of course I'd like to see open protocols for everything, so users can choose the devices from the vendors they want. The internet itself is the greatest example of open interop, and it didn't get that way by vendors playing silly buggers over closed standards. A rising tide lifts all boats. OTOH, individual vendors like Apple and Google will no doubt be looking to tilt the field in their own favour if they can, because that's just business.
Alas, my cheap-ass crystal ball only shows where personal computing will eventually be at, not the exact route it'll take to get there or the precise form it'll take when it does. I suspect much will ride on other vendors not just waiting for Apple or Google to tell them what to copy...
