It has a more dynamic interface. It has Office inside. It can run two apps on the same screen. And it has a USB port and a built-in kickstand. The iPad has none of these things, and the Microsoft Surface does. So why does Microsoft’s first tablet already seem to be on the ropes? According to one estimate, Microsoft is slated to sell only between 500,000 to 600,000 Surfaces running Windows RT during the December quarter, well below expectations. To put this anemic performance in perspective, Apple moved 3 million new iPads and iPad minis in three days. Hope isn’t lost for the Surface. There are some things Microsoft can do immediately to boost sales, as well as some changes the company should make to ensure that there is a second and third Surface.
