Weve done tons of user testing on this, Steve Jobs said in Wednesdays press conference, and it turns out it doesnt work. Touch surfaces dont want to be vertical. It gives great demo, but after a short period of time you start to fatigue, and after an extended period of time, your arm wants to fall off." ~SJobs Just curious what people think on what Jobs said about touchscreens on vertical surfaces. I agree that it's got problems for extended use, but who says it should be the ONLY form of user interaction? A touchscreen doesn't REPLACE the mouse/trackpad/keyboard, it's just another feature available for the times YOU want it. I think his demo of iPhoto fullscreen is a perfect example of when touchscreens would make things easier. Scrolling through tons of photos may be quicker with a scroll wheel but arranging a photobook is a short task where placing images properly works well with your hands. I like what they did with the Apple trackpad but it's no touchscreen. So I have to say that I'm disappointed that touchscreen (likely) wont happen for a long time.
