CNN's Richard Quest will interview two of the top men in the world of IT for an upcoming edition of CNN's Business Traveller.

Quest, famed for his energetic presenting style, will chat to Microsoft chief Bill Gates about future innovations from his company and how the increasing take-up of wi-fi services will impact the future of IT. Quest will also go 'on the road' with Michael Dell, discussing how Dell took a $1000 start-up company and turned it into the company we know as Dell today - which has a $41b annual turnover.

Business Traveller will air this Sunday, January 11, at 20:30 GMT on CNN International.
