PQ Labs demonstrated a new product dubbed as “iTable,” similar to the Microsoft Surface. The iTable has some very nifty features starting with the development side, it has a SDK which like the Surface you can adapt to make your own. The touch screen itself can have only a limited amount of fingers on it at once but the hardware can have as many as you like as its customisable. PQ labs currently manufacture several touch screen technologies.
The iTable runs Windows XP and there's no OSX in sight If you have some application you want to run on your iTable you can because it can run it straight away as long as you map the correct API's.
There's several prices for different models but if you want the economic version then its going to set you back nearly $10,000. You will need to purchase the equipment, which includes Multi-Touch G2 and a 32” LCD Overlay, and then the iTable itself which is $7000. The official 300” version is $12,000 so you are saving money if you go for the 32” overlay.
