The Windows Mobile 6.5 lock screen has some special sauce in it. Now only can you unlock the device, but you can keep it locked and still view whether you have missed calls, new emails, or new SMS. Then, if you slide the respective indicator over to the left, the device gets unlocked, AND you get taken to the correct area of your phone. This should really help to get more done with fewer taps and button pressed when using your mobile device.
