IPhone :: Double Click Home Button

Ok, so now our options for double clicking the home button are Home, Search, Favorites, Camera, iPod, and now multitasking??? 6 options? And if we DON'T want to use double click to go to multitasking what happens... we just lose multitasking all together? Many people have gotten used to and like being able to use the double click for our favorites or for the camera... and now we need to ditch that if we want to use the most desired feature of 4.0??? really? I mean, REALLY? It just seems like a pretty clunky afterthought to throw another double click option at us. Surely apple could have implemented something nicer.

Personally I think for multitasking they should use some sort of 3 finger gesture. Either a 3 finger swipe up (and keep the dock-like implementation apple chose) or a 3 finger zoom out (which would then zoom out to showing all active apps at once. imagine the tabs view in mobile safari.Additionally I think apple should add a dedicated camera button. That would solve the other double home button issue and this would make the iphone much more usable as a camera.
