Exactly one year ago I got my first Windows Phone. Since then a lot has change and Windows Phone has really improved.
After the first update, called NoDo, I could leave my iPhone 4 behind and change to the HTC 7 Trophy. Of course the hardware was nowhere near the iPhone 4 but the Windows Phone OS was just great. Now one year later there is a lot of good Windows Phone hardware out there and the Windows Phone OS has improved with Mango.
I am sure there will be a lot more great Windows Phone stuff in the future.
