As a professional web developer I am now required to create websites that will display properly on all platforms, whether it's desktop, tablet or mobile (phone). The best solution is to use a responsive theme which will automatically scale to the size of the window displaying the site. The Responsive theme does this perfectly using its calculated grid system.
In addition the support given by Emil and Ulrich is outstanding, with quick and accurate responses to all questions.
The combination of expert coding built to WordPress Quality Guidelines and support makes this theme the best. There is no comparison.
