Well, I'm 28 (damn I didn't realize it ). Any way, I had the chance today of installing Jaguar. The speed is about 10% faster than OS 9.2.2, at list until now. I'm in a dual 500 with 320Ram. Stability: forget about that I crashed already 3 times today. Multitasking: 100% I'm doing a render in a soft that runs under clasic while I'm typing this. Navigation: I'm a fish in the water on Clasic, I'll never forgive Apple for chaning the place of things. I hate the way the windows are organize, 5 time slower than Clasic, at list in my case. Dock: Nothing like the Apple menu items, I have to find something that gives me the same functionality. I do not want to have a Dock full of icons. Graphics: 200% better than 9, smooth, clean, fast, not a miracle but really is what I was expecting to get from OS 9 and never found. What I can tell is there was a really big efford from the developers to help you out with your applications, I mean, "things have to run this time no matter what". The really big hit is gonna be OSX 10.5 or 11. But I think I won't delete this version from it partition this time. I did that 3 times before.
