^Once you flash clockwork from rom manager for the first time, you no longer need to access rom manager in order to reboot to recovery. You simply hold down the power button, select reboot, and you get 3 options, restart, recovery and bootloader.
Also, CM7 takes customization to another level. You could never have the power controls available in the notification dropdown with liberty or apex, a transparent app drawer, notification bar at the bottom of the screen as opposed to the top etc...
Aside from the stock motorola kernel, we're getting much of the essence that the og droid had and essentially got me hooked on android to begin with. It's a win for all dev's because they can now work straight from aosp as opposed to the blur elements of previous. now hopefully someone steps up and does a miui port.
