It's time to kill Surface
He's right about one thing: Surface hasn't accomplish any of Microsoft's goals, and at best it remains a niche product. In fact, it has made enemies of its biggest PC manufacturers who are now joining Google to spite Microsoft. Maybe Microsoft should do what Google did with Motorola, and get rid of it. It will never be the cash machine that the iPad is for Apple.
And sorry, but a $930 device with moving parts and ~40GB of free storage, weaker CPU and weaker GPU (but higher resolution, which could make it slower) is not a competitor to the Macbook Air, either. Most people would much rather get the Macbook Air.
