This was fertile ground for all kinds of theorizations and rushed conclusions, ranging from thoughts that Sinofsky has quickly jumped to Apple’s products after no longer being tied by Microsoft to a more sensible opinion that he is just using various products to evaluate them.
And now, the ex-Windows head decided to clear up the confusion with a very clear and concise explanation:
In Office I spent a long time using SmartSuite or Google Docs for the same reasons.”
So it turns out the reason is very mundane with Sinofsky changing devices quite often as he should actually.
