I cannot LIVE without spaces, Spaces, Stacks, and Time Machine, the main feature of Leopard, are my favorite actually. I use each and every single one of them. I can't LIVE without spaces. and yes, i do have a 24"er here, but god, i have 6 spaces setup, and use em all, but use 3 or 4 usually, but on the weekends, i use all 6 😀
