I currently have the Nexus on VZW, I really love plain, clean Android. I have been thinking about selling my spare Rezound and picking up a S3. My one and only issue is that the S3 runs Samsung's Nature UX and after running clean Android I would like to run a ROM that is clean. Im thinking of using CM10 as its the most popular it seems. Reading through the rooting/unlocking thread it doesn't seem to hard, the Nexus was really simple. How does CM10 run on the S3? I'm looking for a stable ROM that doesn't need tweaking/updating a lot, that's the other thing I like about the Nexus clean Android and no issues.
