"Vista sells on almost 100 per cent of all the new consumer PCs around the world," said Ballmer at a press conference at Microsoft’s new Strategic R&D centre in Herzeliya. He also added that the news OS sells "45 percent of all of new business PCs".

The figures might impressive enough, but the reality behind them might not be up to the same standards. It’s true, a Vista license might come as part of the pack when buying a enw machine, but that doesn’t actually mean that Vista will remains installed on the system.

Some PC makers are known to be selling Windows XP downgrades. Furthermore, consumers and PC maker alike have been pressuring Microsoft to continue to offer Windows XP as an alternative to an OS they don’t seem to want.

Last but not least, Microsoft’s next OS is supposed to arrive on the market in two years, thus meaning that the upgrade frenzy will have to start all over again. A perspective not so popular with both home and business users, who would rather wait until then and upgrade to what they hope to be a better OS that Vista managed to be.
