Then why, in 2009 when Windows 7 was released, wasn't Apple able to support it on my computer? I'll answer: Because the video card was so old that ATI didn't bother to write any Windows 7 drivers for it, and Apple couldn't be bothered to write their own. If I buy a computer that promises to be able to run Windows, and 2 years later it doesn't support Windows, it's obsolite.
