I didn't read every reply here, but here's why I am still with Windows Phone.
When I first got my Motorola V600 as my first cell phone, it was great to be able to communicate with people quickly from far away. Every since then, the convenience of instant communication has kept that device in my pocket, along with my Sony CyberShot for pictures. Unfortunately, that was rather clunky, so it had to stay behind and I missed out on photo opportunities often. I also continued to think it would be great if I could access emails, but I wasn't going to buy a data plan for the terrible email interface on that phone.
The next phone I got was an HTC StarTrek (or Cingular 3125) - it was Windows Mobile with a 1.3MP camera. It was nice to have the idea that I'm practically carrying a portable Windows machine in my pocket, while continuing the trend of communication in my pocket, but now with email! Unfortunately, I spent more time trying to find poorly developed programs to make it more usable, and flash it with more simplified firmware to get it running faster than I did actually using and enjoying the device.
Then I upgraded to a Samsung BlackJack II - another Windows Mobile device, but with a keyboard and 3G. My story is very much the same with that device as it was the the StarTrek.
I got tired of Windows Mobile by then, and found that Nokia still made nice phones! I got an E71 with Symbian on it, and a pretty decent 3.2 MP camera. At that time, the camera was merely acceptable, but for the convenience, I largely stopped carrying my Cybershot because I could now take usable pictures and always have them with me. Plus, the OS was stable, device was durable, and it was very portable. Pictures and communication were key, and what I liked.
At some point here, I wanted to try Android, so I got a cheap LG. That was a terrible experience, but it took surprisingly good pictures. However, Android was clunky, and LG's support was non-existent. I went back to my E71.
In fact, I liked my Nokia so much that I said screw it to getting carrier subsidies and bought an unlocked N8. That was the best decision I ever made (phone-related). The 12MP camera was amazing and completely replaced my Cybershot. The Symbian software did everything I needed communication wise, and the OS seemed to always prioritize calls, sms, and email over everything else. I really enjoyed it, though the device itself was a little sluggish at times.
Again, my satisfaction with that device lead me to the 808. Simply the best pictures of any phone I have every seen. I really enjoyed the device and improvements to the OS. Unfortunately, the dated OS was showing, and it became evident that I would never be able to properly use multiple calendars, or properly sync certain aspects of my exchange accounts.
Given the frustrations of the platform, I decided to give WP8 a try and bought a 920. I loved the OS, it was fluid, fast, and did just about everything I needed. Unfortunately, the pictures were just not at the level I wanted them to be. They were more than good, but I felt so disappointed coming from the 808.
As soon as the 1020 came out, I bought it. Now I can carry my camera, access my email, sync my exchange account, and continue to have that original communication I wanted.
Through all of this I discovered the important characteristics: Communication is first and foremost. WP is doing a good job at that, but still needs updates. Photography, 1020 completely fulfills my needs (especially with the black update). The ability to carry a device that lets me talk to anyone, share memory, and store memories is exactly what I wanted, and now I have it.
