Lol, you guys have no sense of the marketplace whatsoever. The #1 reason Windows 8 has not taken off more is that to use it properly you need a touch device and most people do not have a touch device and are not prepared to spend hundreds upgrading.
So, if you can introduce an inexpensive tool which allows users to turn their legacy (i.e., paid for) monitors into "touch screens", this will OBVIOUSLY drive sales of Windows 8.
J5, according to you the ONLY thing that will drive sales of Windows 8 is for the unclean masses to finally bend over and accept it as the future. You must secretly be the Head of Marketing for MS because he has been just about as wrong-headed. So far you have proclaimed that Windows 8.1 won't drive sales, a device which makes touch ubiquitous won't drive sales. Dammit man, WHAT will drive sales other than just blind acceptance?
You are a nice guy but when it comes to marketing you haven't got a clue.
** P.S., The touch protagonists in here have often made the point that touch is the future because we all want to eventually be like Tom Cruise in Minority Report. That's EXACTLY what Leap does, turns us all into Tom Cruise in front of our monitors rather than rubbing our greasy digits across the screen. Do not discount the COOL FACTOR when someone goes into BestBuy and suddenly they can control Windows 8 on a 27 inch monitor simply by waving their hands. And you think THAT sense of empowerment won't sell Windows 8?
Leap will make Windows 8 "cool" and "cool" sells.
