It's easier than ever to pit Windows 7 and OS X 10.6 Snow Leopard head-to-head: They're launching soon, both within a month of each other—and both are basically glorified service packs of the current OS.
In way, they're opposites: Windows 7 uses the same core foundation as Vista while fixing issues and prettying up the outside, while Snow Leopard keeps most of the same spots while re-arranging how things work internally. But the mission is the same—to evolve their current OS—not change the whole game. And launching this fall, we can't avoid a comparison study. The stars of Redmond and Cupertino have never been so closely aligned before.
Snow Leopard socks Windows 7 on both counts here: It's shipping in September for just $29. Windows 7 doesn't hit until Oct. 22, and we've heard it could be pricier than Vista, though it will, on the other hand, be cheaper for people who already have Vista. Nowhere near $29, we bet, but we can dream, can't we?
