I know I'm asking for too much. How about another (user-customisable) button next to the Home button? Or 2 or 3 -- like the old Palm PDAs? It's slow and frustrating not to be able to go *anywhere* with just one or two (or even three) actions (press home to wake up, swipe to unlock, press app icon, or swipe and press endlessly to get to where you want to go).
Also, it would be great to have the option of disabling the "slide to unlock" screen after you press home to wake the phone up. Pressing home would then take you straight to your home screen. Or if you had 3 or 4 hard buttons, you could go anywhere with one action!!!
