Cringely thinks The Next Killer App is telepresence:
Imagine one of the new aluminum and glass iMacs only instead of a 24-inch screen make it 42 inches. The familiar iSight camera will be there in the bezel. but this time the camera will have HD resolution. This hang-it-on-the-wall iMac would establish yet another category of computers, which is what Apple loves to do. They’ll sell a million units to the faithful and all it will take is putting an active telepresence system in every Apple store connected to every other Apple store for prospective users to play with. This gets Apple into the big screen TV business with a system that has higher margins simply because it isn’t just a TV but is also a Mac. Look for all this after Christmas along with refreshed Macs featuring the H.264 encoder chip I pre-announced a number of months ago. Look for Apple to also facilitate telepresence by turning it into a service as it has more and more wanted to do. Then imagine that system connected to a 3G iPhone.
