Im a Research Assistant at school and we have macs and we have OS9 on some of them. I dont know about you guys, but after OS X, OS9 is just like a car with square wheels. It belongs in the past.
I agree. The true multitasking and protected memory in Mac OS X more than made up for the lack of surface level "teh snappy" pretty early on for me. When 10.1 came out I switched over full-time and never looked back...
