My first Windows Phone? That would have to be the Dell Venue Pro. That sliding portrait-QWERTY keyboard? Swoon. It was a little chunky, but I loved that phone. The screen went into a billion pieces when I dropped it on some ice in Park City after slaying the mountain. That was my first Windows Phone, but it wasn't the hardware that really drew me into the mix - it was the software. What made you first buy Windows Phone?
