Microsoft sued over Xbox glitch

A Chicago man who bought Microsoft's new Xbox 360 has sued the world's largest software maker, saying the new video game console has a design flaw that causes it to overheat and freeze up.

The proposed class action claims that in Microsoft's bid to gain share in the $25 billion global video game market, the company was so intent on releasing the Xbox 360 before competing next-generation machines from Sony and Nintendo that it sold a "defectively designed" product.

Robert Byers, who brought the suit, said the power supply and central processing unit in the Xbox 360 overheat, affecting heat-sensitive chips and causing the console to lock up.
