The head of a Whitehall IT efficiency drive is calling for the use of freely available open-source software or Apple computers
Ian Watmore, Tony Blair's former IT chief, urged government offices to increase the use of Apple computers, which he said he used at home, or open products.
He said the move would "dramatically" change the office products game and could help break Microsoft's dominance over the market.
Mr Watmore, who was speaking as the Government launched its IT strategy, told the Commons Public Administration Committee: "I personally would like to see people move off Microsoft products on to open source or use Apple technology.
"I use Apple at home. I know it's not very open but I use it. I love it, it works and I think it is great - I'm Steve Jobs' best customer.
"But 95% of the business and government world still use Microsoft for its basic desktop products because it is reliable and it works.
"I think we, in Government, have an opportunity to change that game quite dramatically, particularly on desktop technology, by getting greater use of open products."
Mr Watmore also claimed that some of the IT fiascos under the previous Government were not because of defective technology but were a result of poor policies.
