Of course, we can put the styles for controls in each windows xaml file. But I am more prefer to all styles storing in a single file, that is more similar with CSS file. If any changes in styles required, you need to modify a single file. That is more manageable.

When I did my shopping at Westfield Carindale, I found there was a roadshow for Microsoft Surface. That was interesting! In front of the counter, there was a Christmas Tree which is made of Surface. That sounds very geek! Beside that, there is something real! There were a few surface 2 and surface pro 2. I tried a surface pro2! That is cool! It has Windows 8.1, not the RT version! Moreover, it has a touch cover, which has a physical netbook size keyboard. That is better than surface which has only a soft keyboard. I think if I have money, I will buy that as a chirstmas present for myself!
