You know how people release comparisons of Mac and Windows before they're even out of (or in) beta? I suggest doing one better! A comparison before there's any information available at all! Interface: Mac interface has changed to Marble, Windows now looks like Snow Leopard. Usability: Exposé has evolved to the point where you look at the icon you want and that program shows up. Windows now has Exposé. Security: Mac is now 100% secure and even has built-in filters against Windows malware. Windows is now susceptible to Mac malware as well. Windows has new feature that asks you every time you press a key on the keyboard if you really meant to press it. Performance: Mac got faster yet, Windows 8 requires double the RAM of Windows 7. What do you think, pretty great eh? I'd say the total from above comes to Windows 8 gets 9/10, Mac OS X 10.7 gets 6/10.
