Microsoft took a swipe at Apple's MacBook Pro today with the introduction of the super sleek convertible Surface Book. The ultra-thin hinged laptop doubles as a tablet, features a removable keyboard and works with a touch, a "Pen" stylus or a mouse.

With a starting price of $1,499, the lightweight, 13.5-inch device -- Microsoft's first-ever in-house laptop -- boasts a full-sized backlit keyboard, 16GB GDDR5 RAM, a 12-hour battery life and a sixth-generation Intel Core processor. The MacBook Pro, which Microsoft claims churns at half the speed of the Surface Book, starts at $1,299.

Panos Panay, Microsoft's Surface VP, asked the crowd as he revealed the MacBook challenger at a Windows 10 devices live briefing this morning.
