This makes a lot of sense. My friends, as Flash RAM gets cheaper the personal computer paradigm of an OS resident on a disk drive goes away. Eventually, virtual memory, hard disks and primary removable media will become a thing of the past.
The desktop computer of the future; think a slab of a printed circuit board with minimal IO (built into the monitor or as a small box like the Mac Mini) on your desktop with a nice big flat screen that you interact with via voice commands and hand movements. Talking with people and talking with your computer will start to create a new lexicon for modern society languages.
Your smart-phone wireless links to it when you are in proximity as needed. All your data will be in your own personal cloud that you manage yourself without any service fee if you want. There will be keyboard and mouse legacy input devices for old school types that field weird interacting with a computer as they do people.
Your grand-kids will see the Window / Keyboard / Mouse interface as we view paper tape readers and panel switches.
Apple has it right, the rest of the world just has to catch up.
