One button madness

So the new iPhone software is coming this summer. It has everything that most people have wanted since the beginning, starting with multi-tasking. Overall it looks like an amazing upgrade and I can't wait to install it on my phone.

I do have one issue with the way it is implemented. Double-clicking the button bring up a tray at the bottom that shows up to seven apps that one has running at the time. Problem is that double-clicking was previously used to pull up either the phone or the iPod functions. What happens to that keystroke now? Is it contextual?

In a way, this is similar to a UI change that occurred one maybe two generations of software in the past. In order to quit an app, one pressed the home button for a long time. That shortcut was changed to a more cumbersome holding of the power button etc.

I love Apples one-button/minimal button ruthlessness but sometimes I think it gets in the way of what they are trying to achieve – ease of use. Remapping keystrokes only serves to frustrate users and lengthen the learning curve. Apple gets away with it sometimes but they should know better.
