Apple may have plenty of announcements of its own to make at this year's WWDC, but it looks like it just couldn't help itself from taking a few jabs at Microsoft as well. Doing the honors was Bertrand Serlet, who took the stage by saying "what a sharp contrast with Vista our OS is," and only got rolling from there, pointing out "what a big hole Microsoft has dug," and adding that "they're trying to get out of it with Windows 7." Of course, Serlet didn't have many good things to say about Windows 7 either, which he says has "even more complexity" than Vista because it's just based on the "same old tech as Vista."
