FYI

There are 3 operating systems Microsoft has
1. Windows on Desktop (the one you use to play steam and ffxiv games).
2. Windows RT (also known as Windows on ARM). I is a different OS and has no relation or compatibility with any other OS.
3. Windows Phone is a mobile OS, and is essentially a rework of the older Windows Mobile OS in response to Android and IOS. It runs your standard mobile apps (eg twitter, facebook, instagram, etc). These are not desktop or tablet tools. The largest Windows phone device is 6" (Nokia Lumia 1520).

If they ever made it available I would use the Libre apps, but I would not use the token as I primarily use my phone for games and business (office/outlook) at work. SE does have a few games out for the phone. I also don't know of any phones that are Steam compatible.

So there has clearly been some misunderstandings. That is probably an issue with the smaller but growing market size, and that everything is called Windows.
