When you are head of a major smartphone platform that happens to be the least popular in the world, it turns out you quickly stop using it.

Joe Belfiore, who works as the corporate vice president of the Operating Systems Group at Microsoft, recently took a year off — as of October 2015 — to take a trip around the world.

Belfiore has been tweeting pictures of his trip, and one tweet in particular shows off his actual preference when it comes to smartphones — the iPhone.

Hey, strangers! Today in Kyoto we stumbled across a HAIR SHRINE! I paid my respects, thinking of all of you! pic.twitter.com/BpsfA4lHKJ

There are a number of replies to the tweet, pointing out that Belfiore isn't using a Windows Phone, and plenty of people are suggesting that Belfiore should be working on making the platform better.

Of course, Belfiore's phone choice likely doesn't really mean that much except the fact that even Microsoft executives aren't huge fans of the Windows Phone platform. Microsoft has also been releasing a number of cross-platform apps, so perhaps Belfiore is making sure to use all the Windows apps while he's on holiday. Not only that, but even Belfiore mentions in an article published by The Verge that it's important for Microsoft to be knowledgeable about its competition.

"To understand the benefits and drawbacks of a full ecosystem like Windows, Android, iOS — you have to LIVE IN IT," said Belfiore in a comment. "You have to feel its strengths and weaknesses, be let down, be delighted. And you can't do that just 'playing around' with a device for a couple of days."
