I like that. That's the reality and they face it.

That's much better than corporate-speak from lala land where there's only Surface tablet and Windows phones.

It tells you nothing about their self esteem, it's about offering products people want to buy. Does selling Microsoft Office for OS X show a lack of esteem? (Hint: the basic Office programs appeared first on the Mac.)

In any case, Microsoft already launched a Universal Bluetooth Keyboard (works with Windows, Android, iOS) last year. It would be a surprise if they went backwards from that.

MS board's corporate strategy is to prioritize cloud services over client operating systems and hardware. Hence the client-neutral messaging.

Google even usually mentions iPhone first.

They guy who is marketing this keyboard is responsible for selling keyboards, so he lists them in the order of likelihood that the reader owns one. Speaking exactly, only 71 people on Earth actually have Windows tablets, so mentioning them first would only serve to make the author seem like a corporate toolbag of the highest order.
