Comment 543 for bug 359392

Noel: sorry, but I think this is BS. Ubuntu doesn't call it's newest version "unstable" or "testing", which would tell the user that it's not safe yet; quite the opposite in fact, if you read the homepage ("you'll always have the latest and greatest applications that the open source world has to offer", etc). So, it would be unrealistic not to expect users to download and try to use new one! When KDE did that with 4.0, they were booed upon by everyone; and rightfully so.

Also, there is a difference between one or two applications not working, or the whole system (from the user's point of view, X IS the system) freezing every 10 minutes. The first could be acceptable, following your rationale; the second, not.
