Here is an interesting article about a Windows power user giving SUSE Linux Enterprise Desktop 10 a trial. While the title of the article itself is a little negative, I think she gives it a pretty fair review.
"Regret is the worst of human emotions. There is no going back with regret. There is no future with regret. Regret is not something I live with. If there is something I wished I hadn't done, I don't do it anymore or I forgive myself and try better. My life is my statement and I try to be true to myself and thusly to other people. Whatever my failings are, they are human and I try to perfect it each day." William Shatner
