Agreed. RSD Lite is very, very quick. Secondly, unrooting takes no time at all. All you have to do is flash the stock ROM and you're good to go. Unroots the phone completely, no superuser app, nothing. It's like you never rooted and it takes a few minutes to flash a ROM. That's what I did when I had to unroot. Didn't even have to use a computer. Downloaded, moved, renamed, flashed. Very easy and fast.
Flashing an unrooted/stock ROM doesn't unroot your phone; you just lack any superuser permissions within the Android operating system, so you're unable to run any app that requires su.
You're phone would still be rooted because you left the custom recovery image (ClockworkMod/SPRecovery) flashed onto the phone. The only real way to unroot is to use a stock sbf to flash both the stock recovery image and the stock ROM, both in one shot.
