Long press Home for Recent Apps and long p;ress Menu for Search is pretty standard on Samsung Galaxy devices and works well on ICS.
Gotta say, after getting a custom ROM installed in my Euro One X that remaps Menu to the Recent Apps button and Recent Apps from a long press of the Home key, I like it a whole helluva lot more. Had that feature not been hacked in, I might well have been tempted with the SGS3 despite how much it makes my eyes bleed to look at the industrial design.
With the hack, the three dot menu thing is gone, and if you hit the new “menu” capacaiive key in an ICS/Holo-Theme app, it opens that top right menu, which is actually MUCH easier than trying to get a finger or thumb all the way up there on a large device like the One X. One something like Chrome Beta where you’re using the menu a LOT to navigate, it’s a godsend
TL;DR there’s always a use case for hardware buttons, and M. Duarte made a few bad calls with ICS regarding navigation.
