I am Graphic designer by trade. It was January 2011, I had never touched a smartphone before as I was upgrading from a Motorola flip-phone so I tested out an iPhone, an android and a Windows Phone. I found the WP software smooth and the UI clean and fell instantly in love with Metro, plus the back button just made sense to me. I picked up my first iPhone and I couldn't figure out how to go back after launching an application. I also have enormous hands and I just found the phone too tiny. I looked at a couple Android devices?which would have been Frodo and Gingerbread around that time?and I thought the UI looked like a cheap version of the iPhone but just felt bad; it was my first experience with Android lag. So after my testing, I went with the Samsung Focus.
I got into buying and trading phones after my first year with the Focus, so my phone experience since then goes something like this:
Samsung Focus, Nokia Lumia 800, Nokia Lumia 710, Nokia Lumia 900 (black, cyan), Nokia Lumia 920 (black, red), Samsung ATIV S, HTC Windows Phone 8S, Nokia Lumia 620, Nokia Lumia 520, HTC One, HTC One S, Samsung Galaxy S4, Nokia Lumia 900 + Nokia Lumia 520, Nokia N9, Nokia Lumia 920 (current).
The reason I keep coming back is because of Xbox Music Pass. I find WP8 music support a step backwards from WP7?especially in playlist management?but its still the best value and offers decent usability compared to the competition.
