Uhh, its not expected, you dont have to install a 3rd party rom. Phone comes with a rom, you could just drive that. I believe the proper response is a big thank you with a thumbs up and a +1. If you dont want to do the "work" involved with backing up, flashing, and restoring, then dont, stay stock. I feel lucky to have such a wonderful development community doing there thing making our phones, something to enjoy not just something to remember before you leave the house.
Well said! And as always, a big thanks to the great group of DEVS out there who are keeping our red-headed Motorola step-child fresh and exciting!
Cheers
