Contrary to popular belief Microsoft doesn't really care what phone you use. Nor does it care if you use an iPad or Mac at home. I'd wager most Microsoft employees use Android, with iOS as close second and WP as distant third. A lot less distant than in the rest of the world, but third nevertheless.

MS employee here. Most of the older employees use Windows phones and most younger employees use iPhones. I was honestly surprised how many people own Windows phones.

And no, bosses/execs don't care what phone you have.
