This thread is interesting to me as I HAVE been fully rooted in the past, with NAND unlocked permanently. (S-OFF). I had to unroot in order to return my EVO to Sprint for a new one due to some dead pixels.
I WAS going to wait until UnrEVOked comes out with a new version to work around the latest update. Temporary root is fine for freezing/removing the bloat, but the reboot and lose root would kill me. Therefore, I rooted, with the latest OTA the hard way.
I'd be patient and wait for a FULL root. The advantage of this is two fold, with clarification:
1. You get updates ie: 2.3 or 2.5 via a custom ROM faster than you would with an OTA update from HTC or Sprint.
2. Keep in mind that if you permanently root, you will never take another OTA. You now have FULL control over your EVO! You will have to flash a ROM, (and there are plenty of hard working people who create stock ROM's if you want over at XDA.com) and flash new ROMS for Gingerbread (and there are some out there now..just goes to show how much faster you get the goodness of Android when you're rooted!)
Peace.
