Bill Gates thinks he's going to one-up Apple by making touch screens obsolete. Hmmm. Sure, you could flick left and right on your phone or computer by waving your finger in the air, or play video games by waving your hands in the air... but if you want to click on a specific button on the screen, you can't just point to it. The margin of error would be huge. I think touch screens are always going to be required for certain tasks. Maybe a hybrid concept will be implemented. For certain commands, you can just wave your finger...for others, you will need to actually touch the screen.
