Microsoft has been on a whirlwind promotion of their new Windows 10, and with several devices aside from that of Microsoft receiving the said OS update, it is understandable seeing Microsoft CEO Satya Nadella all over the news.

According to the International Business Times, Nadella spoke during the company's Future Decoded conference in London and demonstrated how powerful the Windows 10 has become on different platforms. Demonstrating how much Microsoft has adapted to other devices, Nadella showed an iPhone device as an example of another platform that runs some of Microsoft's apps. Up on the big screen was the home screen of what he called the "iPhone Pro," unfortunately, it wasn't his.

But to give you an account of what was on the home screen and by tracking how the Microsoft CEO spends his weekdays, it does have something to do with meetings, schedules and email correspondents. A person who dedicates his time entirely on work definitely shows something more appropriate on his own cell phone screen.

The iPhone that Nadella introduced during one of his talks featured the Outlook Email App, something that he strongly believed to be the best email client for both Exchange and Gmail. However, to lighten the mood, Nadella revealed that the supposed "iPhone Pro" he was using as an example was not his personal phone and quickly declared that his personal phone is the new Lumia 950 XL unit.

Nadella went on to discuss the Lumia 950 XL's Wunderlist app, which combines list-making and other collaborative tools within the device. Using the list, which was subtitled as "Homework," Nadella made a list of his "To Do's" including Hololens Note, brainstorm global tour and prep personal story.

The Continuum feature of the Lumia 950 XL was also introduced by Nadella. Here, users are able to connect the device to a monitor or through Bluetooth and get the maximum PC experience. He also took the opportunity to introduce the Microsoft Surface Pro 4 using its facial recognition sign-in feature.

TechRadar was able to get a hold of some of Nadella's favorite apps and games and apps, and they include Snap Attack and Despicable Me: Minion Rush. During his introduction of the Lumia 950 XL, where he also introduced it as his personal brand, Nadella has in his hands the latest model of Microsoft's flagship phones. It's easy to believe that he does use the Lumia line given how much Microsoft invested time and idea on their latest devices.
