Vista only hit the shelves yesterday, but Microsoft's new operating system has already sent shockwaves through the PC retail industry.

Want to get your hands on an Acer desktop bundled with a copy of "Genuine MS Windows Vista Premium"? Get prepared to fork out a wallet-thrashing £9,999 for the pleasure, if prices down at PC World are anything to go by:

With Vista retailing at only £219.99, the addition of the operating system has pushed prices sky high with the desktop itself ringing in at a whopping £9779.01.

While PC buyers will be crying into their cheque books on the news, we're sure there'll be high fives all round at Redmond - which certainly has succeeded in achieving its 'wow' factor. ®
