It's not as if Microsoft voluntarily got nicer. They did every dirty thing they could to dominate the PC industry and simply failed. Now they're beginning to steer their leaky ship in a better direction, good for them. For me personally, I'll never be a fan of the company that selfishly held the web back with IE for a decade because they didn't want to compete. Sic semper tyrannis!
