The iPad has the highest customer satisfaction ratings of any tablet in the world, but Microsoft cofounder Bill Gates thinks that many of its users are “frustrated” because it doesn’t come with a physical keyboard and it lacks access to Microsoft Office. Business Insider reports that Gates, while being interviewed on CNBC on Monday, said that a lot of iPad users “are frustrated, they can’t type, they can’t create documents, they don’t have Office there.” As an alternative, Gates plugged Microsoft’s own Surface Tablet.

Sadly, many iPad users are clearly not frustrated. And once upon a time lack of office editing would have been an issue. But there are many third party apps available now that provide office docs and editing. Then there are alternative cloud solutions like Google Docs.

I think the Surface Tablet is a good idea, but it just might be too late into the game.
