LOVE your layout, but hate, hate, hate the logo!!!!! I think that it would be better to use a different font for your logo and lose the drop shadow. It would also be better to get rid of the logo's white background and have it blend in with the blue header. Right now, you've got this blue logo and white background cutting into a blue header, and it doesn't look cool. I would design a new blue header with techie stripes with maybe a faded airplane graphic or something. Other than that, I think the layout is very good!
