So as of now I have leopard at home, I have been using it on my PPC g5 running CS3 apps. Slightly testing it to see what kind of issues I could be having. I still feel it is buggy, (especially ID) this could be a g5 thing. At my work I have 4 g5's and 1 mac pro intel. I would like to keep everyone on the same page, but I will be purchasing another Mac Pro, with leopard on it. Anyone in this boat? Should I upgrade everyone, or just leave the one person with leopard while the rest of us work in tiger? Thanks!
