How many of you are just fine using 10.5.8 and find no need to upgrade to Snow Leopard? This reminds me of the company I work for which has all company PCs running on XP and refuses to upgrade any company computer to Vista for the time being. I know, I know, Mac OS is way better...but I've read about incompatibility issues and it makes me wonder, what's the worst that can happen if I decide to wait a good 3-4 months to do the upgrade?
