Just to chime in here, I have a desire for root, but I'm still stock/no-root.
I know folks might disagree with me, but after reading pages and pages of howto's, etc. I've determined there is no way to backup your stock phone (TA partition/DRM keys) etc with any of the current methods.
To root you must unlock your boot loader, when you unlock your bootloader, your TA partition and DRM keys are gone.
This means you have voided your warranty and can never restore to a truly stock phone.
Yeah Yeah Yeah, I know you can revert all the way back to version 532, root the phone and then backup your TA, etc. This is a WHOLE lot of steps that if you aren't careful can leave you with a $700 brick. If your nervous at all about these multi-step processes, than just leave your phone alone.
As many have said, I really haven't even thought about a custom ROM for this phone. The ONLY thing I miss is being able to do a nandroid backup, as it's such a pain to rebuild my phone if something goes wonky.
