Is it just me or does the 300ms+ delay after hitting your home button before it goes back (in all versions of iOS) drive you absolutely and utterly insane? Navigating an iPhone is like walking through molasses. I can understand there being a tiny delay to OPEN apps, but to go back should be instantaneous, like hitting the minimize or close button on a browser window on a desktop. It feels like it's been designed into the OS intentionally and if so, the engineer who thought it served a purpose should be fired, then drawn and quartered, then burned, then imprisoned for 42 years. Or... at the VERY least scolded and ordered to remove the delay.
