Anyone who's ever read Douglas Adams' HGTTG knows the value of having a traveling companion you can stuff into your pocket.
Something that you can rely on being with you day and night, no matter where in the world you are or what set of clothes you're wearing 🙂
Something that keeps track of your schedule and answers your questions before you ask them.
For the Premier Field Engineer rangers - this something is the Windows Phone with the internal Microsoft business app suite.
As Tolkien might have put it (at least if he'd had a Windows Phone and been a PFE)...
One App to rule time
one App to find it
one App to Bing it all
...and in the darkness sync it with the internal Dynamics server
In the land of Microsoft, in the PFE life
