I just got a Razr Max HD, coming from a Thunderbolt that ran CM7 since it was available. I absolutely loved the lock screen on CM7. I had it set up to show a wallpaper that had company information, contact info and a legal warning for anyone who found or stole the phone. I also added a "slide to unlock" graphic on the bottom so it looked like that was how it unlocked. I set the gesture to leave no trails so anyone who picked it up would keep trying to slide to unlock and get nowhere because they couldn't see it was making gestures. Then, of course, I had several application shortcuts for things like camera and flashlight which were priceless to me. I would most definitely pay an unreasonable amount for an app if someone could replicate the features that lock screen has. I miss it tremendously.
