A couple of weeks ago I was seriously considering not upgrading to Jaguar because of all the tales of woe on this and other Board's. After some reassurance from the great Mac community I went ahead and upgraded after backing up and waiting for a lull in work. I chose just to "upgrade" rather than a clean install or the archive option. The installation was flawless and the system is just as stable as it has ever been. I have a Ti400 so I haven't seen any noticeable speed increase (8mb video card), but it's fast enough and stability creates greater efficiency, in my opinion. I used to crash several times a day with 9. I think I've only had one or two lock ups with OS X and I'm pretty sure Navigator caused both. So, I just wanted to let others know it really isn't that scary out there and I don't think you have to be a superhero and spend all day reformatting and reloading all of your programs and data. 
I wish I had a 933. You know though it aint none to slow on my 466
