If you're aiming for simplicity and something revolutionary I would suggest going with something so basic and dull. You need more colors than just gray, excluding the icons. If you're looking for someone also that's 'fluid' for everyone yet makes your life easy, I would make the width just a narrow container with centering margins. A width of 960 should be fine for a container.

You should also look into creating a metro themed page, it may go towards your "revolutionary" and simplistic idea.
