I have an HTC Windows 8X phone. I work for a Microsoft Partner, so this seemed like a good idea at the time. After nearly a year, I can report that I am tired of this phone and want to go back to Android.
The one thing my phone does well is manage two Microsoft Exchange accounts. And it does Skydrive all right too. Those are Microsoft products, so Windows should handle them.
I find the touch-screen waaay too sensitive. It can't determine what letter I want more than half the time, and its auto-correct suggestions hardly ever make sense.
Bing, however, sucks ass, compared with Google. And there's no way to change the hyper-sensitive search button on the phone, which fires up Bing every time my thumb goes near the search icon. Sometimes when I'm trying to take a photo, or do something else that involves the phone not switching applications.
Bing Maps is even worse. I won't spend too much time on a rant when I could just show you.
Let me preface this by saying Seoul's WiFi situation is amazing. I have free WiFi nearly everywhere I go. Which is how I was able to run the following comparison.
Exhibit A, where the Bing Maps application thought I was this afternoon:

Exhibit B, where Google Maps thought I was at the same moment:
Note that the Bing Maps application on my phone failed to produce a usable map; Bing Maps itself has the data. Here's what the Bing Maps website shows inside a browser window:
Attention, Microsoft: Having a nicely detailed map on my laptop does not help me when I'm in the middle of Gangnam. That's really exactly the moment that I want a good map.
Oh, and to add insult, Google Maps doesn't really work that well on the IE11 mobile browser. As in, it won't search unless you really make sure you touch exactly the right pixel on the screen.
My next phone? I'm going back to Android.
