I love the Multitouch touchpad on my unibody macbook, its the first time ever I have considered a touchpad superior to the mouse (infact it made me bin my mouse). The problem is if you own an iMac or mac mini or pre october 2008 you cant enjoy this enhanced UI. Apple need to update all its keyboards with Back Lighting & multiouch Touch pads, the bluetooth model needs a mini usb port to charge it rather then swapping batteries. One device that has opened my eyes is the PS3 keypad it has stroke sensitive buttons so you can actually make the mouse pointer move like a trackpad by moving your finger over the buttons without actually pressing them. If apple could reproduce this technology on its larger keyboards?
