Ask Slashdot: How Often Do You Update Your OS?

An anonymous reader writes: A couple friends of mine have been having a debate recently. One is constantly updating all of his operating systems, often as soon as a new patch is available. He tries betas and nightlies. He has a different ROM on his phone every other week. The other friend is much more conservative with his updates. Once his systems are running smoothly, he wants to leave them alone for as long as possible. He'll do some serious security updates, but he's extremely wary of anything involving major UI changes or functionality differences. What's your preference? Are you constantly tweaking? Waiting for the early adopters to work out the kinks? How does your preference change between work machines and personal machines?
