I'm a little concerned about upgrading to the latest OS, having read about the problems others are having. So I'm probably going to wait awhile, I think, before taking the plunge. Why should we, as AppleHeads, have these trepidations regarding doing a simple upgrade. Not a very good situation! This got me to thinking (now that is a reason for some concern). Why don't the "powers that be" put out a Beta version first, so some of the kinks can be worked out before the Mac public gets their hands on it? Just musing, I don't have an answer!
