“You Probably Already Read This”

If you're a mac aficionado, then you've probably already read it. If you haven't, go read the ultimate Mac OS X Leopard (10.5) review by John Siracusa.

It's not an exhaustive review of everything new or different in 10.5, but it's still quite long. Worth the read if you use a mac every day. Some of it is quite technical, but the review is broken across a number of pages so you can skip the parts that don't interest you.
