I installed Snow Leopard a few days ago - Fusion kept going. It's working perfectly, in fact. I'm really happy and my wife is happy because the combination of Snow Leopard and Fusion lets her get our monthly billing done. But I'm a geek so I'm more happy. Tonight I installed RedHat 5.4 - a new release. On Snow Leopard running Fusion 2.05. VMWare tools installed perfectly, Fusion works, RedHat 5.4 works, Unity works, printing and drag/drop works, and I didn't even bother reading the readme.txt files - it just works. I like that. Fusion - it's resiient. Even when nobody's looking.
