Yea, that's the advantage Mac OS has had over PC's as well, only having a small range of hardware to deal with so they don't have to worry about compatibility issues with 1000's of different motherboards, ram, video cards etc, which is why the OS has always felt more polished and just works.
I know the Thunderbolts hardware blows away the iPhone 4, but the new iPhone will be out in September and will probably have dual procs, better screen, more ram etc. I might just hold out a little while longer to see what other droid phones come out at that time and do a comparison.
