I consider myself technology agnostic. That is to say, I love trying new gadgets and tech, regardless of brand. I can see the benefits (and drawbacks) of each platform and I tend to enjoy changing things up every once in a while.
Gaming Console
I don't own an XBox. I haven't been a heavy console gamer since I sold my PS2 back in the day. I have a Wii, but my son uses it most of the time. I play a few PC games (on Windows), though.
Desktop/Laptop
Currently, my personal desktop and work desktop run Windows 7. My work laptop runs Windows 8.1. I've tried various linux distros off and on (Ubuntu tends to be my favorite), but I always come back to Windows. I used a MacBook Pro at a previous job for over a year, but as much as I loved the hardware and OS, I had to switch back to a Windows laptop because it was more compatible with the apps and systems I needed to use for work. I wouldn't mind owning a Mac, I can just never bring myself to justify the cost when I know a Windows desktop/laptop is perfectly capable of doing everything I need. I'd probably end up using BootCamp or Parallels to run Windows on a Mac, anyway!
Smartphone
Currently, I'm using a BlackBerry Z30, and I consider it to be the best smartphone I have ever owned. Before the Z30 I had an iPhone 5. Before that, a Lumia 521. And before that, a Galaxy Nexus.
I was thoroughly impressed by the Lumia 521 and still consider it to be the best smartphone for the price. It was just a bit too "entry level" for me and didn't keep me hooked. But I'm glad I tried it because it gave me some valuable insight and experience with Windows Phone.
Android and iOS no longer interest me. BlackBerry is focusing on things like the enterprise and the Internet of Things, and while it still intends to produce handsets for the foreseeable future, it's all but conceded defeat in the consumer smartphone market. It makes great devices, but its ecosystem is lousy and it has to depend on the ability to run Android apps.
My next smartphone will most likely be Windows Phone for many reasons, including integration with Microsoft services, amazing hardware (Nokia - DAT CAMERA), and overall stability and steady growth of the platform. Also, I'm done with Apple and Google - I could write a series of posts on that topic alone.
Cloud/Other
I use Outlook.com as my primary personal email service. I have my Gmail and other accounts forwarding to my Outlook account. The interface, for me, is easy to use, looks great, and is very well designed.
Office Online is my preferred cloud-based productivity suite.
Calendar and contacts are fantastic.
OneDrive is my preferred cloud storage service.
OneNote is my preferred tool for jotting things down and being able to access them from any device.
Summary
Though I don't use or prefer tech solely based on brand, and I enjoy using and tinkering with all kinds of different tech, I find I've naturally gravitated towards Microsoft more than anything else.
Microsoft's products and services seem to fit my personal preferences and style more often than not.
