“Here’s the test I use to determine whether a new computer OS is a success: If I am using both the older operating system and the newer one, do I miss the latter when I’m using the former?

“Overall, Leopard’s a winner. If you’re a Mac user, you will want this on your computer,” Silverman reports.

If you’re a Windows user who’s been tempted by the Mac, I’m not sure there’s much here to add to the siren song you’re already hearing. But if you make the leap, there’s a lot in Leopard to make you glad you did,” Silverman reports.
