...Something along those lines. Let's extrapolate the future from Apple's current lineup. We'll disregard everything about the design (because it will ALL need to be changed for system-wide multitouch to be feasible) except for the screen right now.
Apple is moving to only glossy screens. As much as people who love matte hate it, they're doing it for a reason. Apple's newest glossy screens aren't like those in the plastic MacBook; they're optical quality glass. Now, what's the iPhone screen? Optical quality glass.
It's a smooth transition on all fronts. You can see the beginnings in almost every aspect of their hardware and software designs now.
The screens are going glass for a reason: eventually we'll be touching them. It's very nice, touching the iPhone's screen. The interface is intuitive, and typing (in landscape mode) is easy, even on such a small screen.
The iPhone is a test. As much as the MacBook Air was a test for the unibody enclosure, the iPhone is a testApple's first baby stepsinto OS XI.
The "keyboard" in OS XI will be full-size; not a problem when we're dealing with the larger screens of portable and "desktop" computers (the definition of a desktop computer will have to change entirely with Apple's OS XI designs, but that's something for a different post).
Some people complain about the iPhone keyboard not having haptic feedback, but with a full-size keyboard, most if not all of these complaints are gone. We'll see what Apple does; they have a touch-haptic patent under their belt that looks very nice.
The "keyboard" in OS XI will operate much like the keyboards of today in function and much like the keyboard of the iPhone in input style. It will appear in the OS XI interface when needed and not be there when it is not needed.
Such a concept is difficult to imagine, what with the myriad of keyboard combinations one can do throughout the OS X interface right now. But OS XI will do away with the necessity for keyboard combinations. You will be able to do to the GUI of OS XI with your hands everything you can do with a keyboard now and MORE.
I, for one, am very excited for the future of the GUI. It is difficult to pin down exactly what Apple will do in removing the keyboard... but we're already seeing it happen, now aren't we? That trackpad on the new MacBooks... four finger gestures operate Exposé controls, right? Well... now there is no need for the old key presses that would do the same thing...
You see? Apple knows what they're doing. It's a beautiful thing.
Oh, glory me. Look at this. I did the same thing when I explained why Blu-ray won't show up in Macs until 2015. I do apologize for the length, but I feel that it is necessary. You have to cover all the points you can when you argue in favor of something. And, as you can see, I haven't fabricated anything, just extrapolated from what I've seen come out of Cupertino.
