I like the screenshots but I don't understand the navigation of the page and why would you hijack the default scrollbar of your browser?
I'm surprised that so apps look WP metro style

I'm guessing this was designed by someone with a multitouch trackpad. I know I tend to forget not everyone else has 2 finger scroll at their fingertips, I've had to get into a habit of having a test run using a mouse when I put together pages.
Those of us using multitouch trackpads can scroll by just swiping on the page using N fingers, like scrolling on a touch phone by dragging the page with your finger.
