I am thinking of buying Leopard, but I just don't see the benefit over Tiger. New functions with the iPhone and iPod would be deal makers for me. I am not a heavy user, I don't use ichat for more than ims, i don't use windows, and i dont think i really need time machine. There are some neat little tricks and interfaces with leopard, but I just don't see them being worth 130 bucks. I'll probably get it anyway, (I am a sucker for Apple products), but I really need to justify it. Any ideas on something I might be missing?
