I returned the win hd today (and if you bought it online from Microsoft and expect a breezy refund or exchange from b&m think again). Anyways, the Win Hd is a very nice looking phone, and the the display looks beautiful and plays video very very well (after update). BUT , it isn't powerful enough,. For instance it can barley run candy crush (1/3rd speed). It is very laggy. Slow scrolling is extremely choppy. The touch sensitivity is horrid. Even after updates and enrolling in developers early preview, I would constantly click on a link or app when just trying to scroll up or down and it will drive you nuts. Also, good luck using dual sim function.
In contrast, he lumia 635 runs as smooth as silk and you don't accidentally click on links or launch apps while trying to scroll. It even runs candy crush full speed. Plus it has gorilla glass and you can actually buy cases for the lumia.
So, what I did was returned the win hd and got a no contract tmobile lumia 635 for $79. I walked out with a better phone plus the $100 difference in my pocket.
