Apple says that consumers may turn to Mac computers because Microsoft's new operating system, Windows 7, is 'complex and expensive':

The criticism comes from Brian Croll, vice president of Apple's Mac OS X worldwide product marketing. He said that Microsoft users were tired of the "headaches" caused by the Windows operating system, and expects some disillusioned Windows users to switch to Apple's Mac platform.

"Windows users are really tired of all the headaches that they've been getting over the years, starting all the way back from Windows Me to NT to Vista and now Windows 7," he said. "As a result, I think people are looking for something different, and the Mac offers real ease of use, stability and security."
