Under PR1.2, if you lock your screen and then click the power button to display the "swipe to unlock" screen, it now shows icons and numbers for any and all missed calls, SMSs, and Voicemails.

This is pretty good for me and readable from only a glance instead of having to be on the desktop that a widget may be displaying the same info on, and certainly faster then clicking the "menu" button to look at the standard notifications.
