I was set on getting an Android phone after my Windows Mobile phone.
Unlike many others, I was actually happy with Windows Mobile. I didn't like how slow my Fuze was, but I did like the workflow. I liked the accuracy of a stylus. And I was addicted to Solitaire. I was insanely fast at it. And I would keep trying to beat my best time. lol. I also liked how I could draw pictures with the stylus.
My sister let me borrow her iPhone 3GS for a month, and I did love the screen and the apps that were available. Heck, I finished Angry Birds (it was only 90 levels at the time) in 3 days. I didn't like any of the Solitaire apps available though. They all seemed so slow. I think having a stylus was an advantage in that sense.
So, anyway... after about 2 weeks of trying the 3GS, I went back to the Fuze and let my wife play with the iPhone for the last 2 weeks. I just liked my Fuze a tiny bit better.
But I started researching Android like crazy. It seemed like the closest thing to Windows Mobile... but updated with more modern features like the iPhone had. I was sooo close to getting one. Just was waiting for my contract to be over.
And then MS announced Windows Phone. And well... it was done. I was sold instantly.
