There are many instances I wished I had touch capability on my Macbook Air. And I stumbled upon the AirBar. This seems to be a great add on to my Macbook Air at a very attractive price. It costs under $100 in amazon right now. I have not personally used it yet but is on my list for sure. Please let me if know if any one had used it. I would like to know if it is accurate in picking up the gestures and is worth buying.
