On the iPad Home Button

Dave Caolo:

There are eight functions the iPad Home button performs. As far as replacing it with a touch-sensitive area on the bezel, that’s just impractical. The main problem is orientation. Where is it? Since there’s no “wrong” way to hold an iPad, the Home button could be at the top, bottom, left or right at any time. I often find it by feel, a tactic that a touch area would eliminate.
