The day is coming when only one out of every few people will need a traditional computer, said Steve Jobs at the D8 conference.

“When we were an agrarian nation, all cars were trucks because that’s what you needed on the farms.” Cars became more popular as cities rose, and things like power steering and automatic transmission became popular.

“PCs are going to be like trucks,” Jobs said. “They are still going to be around.” However, he said, only “one out of x people will need them.”

Jobs said advances in chips and software will allow tablet devices like the iPad to do tasks that today are really only suited for a traditional computer, things like video editing and graphic arts work.
