Samuel, 1 button on the Face of the device. But the magic of the way that the iPhone (and most technology) works is that if you mis-click, just do it again. If you're on a PC and try to click on something and miss, you just IMMEDIATELY attempt again, right? Why is this any different with a button on a device? I sometimes try to double-click to pull up the multi-tasking bar so I can mess with my music from within another app, but sometimes I only single click. No biggie, just immediately double click, fix my music, then pop back into what I was doing. My only gripe is that maybe I want to change how *MY* home button works. It's my phone, let me make double clicking the home button skip to the next track or open my camera app. Now *that* would be awesome.
