Erik Love writes "Esteemed British newspaper The Economist, reviews Windows Vista. They love it, but advise WinXP users to wait awhile before upgrading: "Many say Vista's problem is its sheer size and complexity. All told, the program comprises some 50m lines of computer code. And as any programmer will tell you, software contains typically five to ten errors for every 100 lines of code. So, even if 90% of them were squished during the extensive testing programme, Vista will hit the shelves with at least a quarter of a million bugs in it.""
