iOS 4 on a Mac?

Here come the flood of predictions on Apple’s OS strategy. Adrian Kingsley-Hughes:

Pre iPad, it made little sense for Apple to even think of putting the iPhone OS on the Mac, since the apps were specifically designed for a small screen. But with the iPad, Apple is now building quite a repository of apps designed for a far bigger screen. It’s not hard to imagine apps designed for the iPad such as iWorks or Documents to Go working on a MacBook, MacBook Pro or MacBook Air. Rather than being driven by a touchscreen, the OS would simply take commands via the keyboard and trackpad.

Farfetched? So was switching the Mac to Intel Inside and allowing it to run Windows.
