I'm the system administrator where I work... my boss, the Director of IT, has a Galaxy S3 but is interested in the WP platform... he just hasn't bothered to make the switch, because he's not upgrade eligible right now. We also find it helpful to have an Android phone around for support since most of our staff has them. He, like me and our desktop support specialist, is definitely a Microsoft guy. He hates Apple, possibly more than I do. Our desktop support specialist is on Verizon and has a Trophy. She's not eligible for an upgrade yet either, but she really likes Windows Phone too, but not the 920... says it's too big for her hands. She prefers the 8X. She would never own an Apple and finds Android to be overly complicated.
Everybody else knows not to trash WP around me... because I challenge them back. I'll pull out my phone and ask them, show me something you do on your phone every day... then I pull a Ben Rudolph and show them how much faster and easier I can do it. And even now with Lenses like CamWow, I can beat them on the Instagram stuff. Honestly though, most people are quite impressed when I show them my 920... it's red, so it really stands out, and once I show them a few features, they either grumble about their phone or they cling to their phones like it's "my precious". I was having a conversation with a coworker about the Lumia (he specifically asked), and another one (a girl with an iPhone) interrupted just to say, "I love my phone too... it's awesome." I just ignored her and continued my conversation, using my phone display with a key.
