For developers willing to shell out $99 for an annual membership in Apples group of Mac OS app creators, Lion is old news already. But the rest of you can finally download Apples latest operating system — Mac OS 10.7 — by hitting up the App Store on your Snow Leopard 10.6.8-equipped Mac, assuming its powered by an Intel Core 2 Duo, Core i3, i5 or i7 processor. From our experience with the pre-release version, the 4GB download could take over an hour, even on a high-speed connection, but once you have the installer in hand the upgrade process itself should be complete in about 20 minutes. Well be posting a full review of Lion later this week, but you can check out our hands-on preview for a sneak peek at Apples latest consumer OS in the meantime.
