Mohammed. I agree with you about -showing- a 'piechart'<br><br>The iPhone 'flick' scrolling is possibly a new standard in small form factor (sff) interfaces. We can now expect users to expect a similar interaction on all lists in mobile devices, to a certain degree.
<br><br>I would suggest changing the line in the wiki "In essence, a 4-way

inside a scroll list. "<br><br>To "In essence, 4 way scrolling is enabled when a mouse-down event is encountered
inside a scroll list. "<br><br>You said "and all they where able to do is either single-click, double-click and drag for almost as long." This isnt strictly true, Mac users have used the Apple key in conjunction with the mouse to do right clicks. I would be -very- wary of drawing any comparisons with desktop OS's.

In related news, we did some usability testing on the iPhone, women with fingernails could NOT use the iPhone keyboard!! (o;
<br><br>Also"************<br>So I believe to simplify the touch interface:<br> a. single-tap would equal a single click<br> b. tap&hold would represent a double-click<br> c. a drag would mean a scroll in that direction
