Here is an idea I though of that I'd like to share and discuss. No idea if its been brought up before. I think the next big step in the evolution of the track pad on MacBooks (and the stand alone peripheral for Mac desktops) will not include any new technology what so ever. It will take a technology that Apple has already perfected and simply apply it in a new and ingenious way. I think the next generation of track pads will be iPod Touches/iPhones. Or at least the displays. Track pads won't just be gray glass plates you can use to provide input, they will be displays providing you with output and feedback as well thus bringing the level of input you can provide to a whole new level. I think the next step after that will be expanding the track pad to include the entire area below the keyboard, including the palm wrests. Thoughts?
