24-inch LED Cinema Display knows that it's hard to lay off on the touching. No one knows that better than Troll Touch, who has just announced a touch panel integration kit for Apple's freshest LCD. The touchscreen gets powered internally via USB, and the custom touchscreen overlay design doesn't alter the panel's form factor in any way. Those looking to dive in from scratch can order a touch-enabled version now for $2,299, but those looking to simply upgrade their own can ship it to Valencia, California along with $1,399 marked for integration. Talk about a steep price to pay for permission to touch.
