Microsoft CEO Steve Ballmer is known for his bellicosity, and he’s rattling the saber at Apple. Despite the fact that over 100 million iPads have been sold, he doesn’t think any tablet has serviced customers the way that Surface does.

“I don’t think anybody has done a product that is the product that I see customers wanting,” said Ballmer. “You can go through the products from all those guys…  and none of them has a product that you can really use. Not Apple. Not Google. Not Amazon. Nobody has a product that lets you work and play that can be your tablet and your PC. Not at any price point.”
