Oh no, Leopard won't be crashing the Vista Party. I just read
this on Paul Thurrott's Internet Nexus. As diligent readers know, I'm still using Panther, or OS X 10.3.9, for those who use numbers. There's a slew of interesting software that only runs on Tiger, OS X 10.4, which I will list later. I'm loathe to buy a Mac until I can get one with Leopard pre-installed.
