Troll Touch has introduced a new touchscreen adapter for Powerbooks. Simply place the SlipCOVER over your screen, and plug it into a free USB port. Viola! You now have a touch screen Powerbook. I personally have never been a huge fan of touchscreens. No matter what one does, greasy finger marks end up all over it. The Troll Touch site shows no price for the product, but I would expect it to be quite a dent in your wallet. SlipCOVERs are allready alaviable for 12″ iBooks, and there are plans to release SlipCOVERs for Apples entire portable line.
