Defenestration
The loss of Steven Sinofsky seems as though it would hurt Microsoft sales significantly. He was head of a division that contributed about a quarter of the company’s $74 billion in revenue which means if Microsoft doesn’t choose their new head carefully, their sales could definitely suffer. As to why he left the company? It’s still a mystery. But why does anyone quit their job? Maybe it was his work environment and he wasn’t satisfied at the job anymore, after 20+ years of working there. Maybe it was his team of workers, or something more personal like family. Whichever it may be, the loss of Steven Sinofsky will hurt the Microsoft team greatly.
Furthermore, I tend to agree that the use of tiles may confuse consumers, while using Microsoft 8. It’s an interesting concept, albeit, and maybe more efficient as well, but it’s something far beyond what the typical Microsoft consumer would know how to use. It can really sway their popularity either way.
