Changed Navigation Layout

I have made the decision to change the main Navigation layout that displays when the site is being viewed from iPad landscape and up. I decided to do this due to the graphical style of my site - there are little 'real' images and my initial design focused on having a large slideshow that ran to the fold of the page. When I created this it did not look right, so I have adjusted the navigation so it appears as the following:

iPad Portrait

I have stuck with my previous decided navigation for the mobile version
