I'm working on a new version of a corporate website. As it stands, it has about 6 different sections. Each of those sections have between 3 to 6 sub-pages. My nav is at the top of the page and looks a bit like the wireframe below:
I have made some simple dropdowns with js to handle the desktop side of things. For tablets and mobile devices I have gone with the standard right aligned hamburger menu button. The more I look at the site on a tablet, the more I like the lack of clutter at the top.
Apart from potentially confusing some users, what are the downsides of going with the hamburger menu for all devices? http://www.squarespace.com/ and a number of other sites do this already.
