It seems that while Microsoft might have kicked off the revolutin with using images instead of text, its the touch and gesture based devices that are exploiting that prophesy to the full extent. Touch based devices arent expensive and with their prevalent availability as third screens, they will occupy a very crucial space in the hands of decision makers on the floor - be it stock traders, doctors, CXOs etc. There are countless applications that one can think about on that space (beyond angry birds)
What we are even more excited about is the kinect. With the availability of the device and drivers for PCs, and with the way Windows 8 is spanning out, it wont be mice or keyboards, but gestures that will take full advantage. But the applications of it can change entire industries. Take for example the publishing industry: its run on a deadline and newpaper industries run a very tight ship in controlling the layout of their publications. What if we could have layout applications that can throw the entire layout on a large screen and using gestures allow to rearrange articles around, and optimize for best impression and design? Or an app which will allow you to sit at home and scroll through a shopping catalogue.
Rather simple applications, but the implications would be very profound. Why the wait then?
