Awesome use of colours and grids in a page so informative it (kinda) hurts. I love it.
What I’d like to see differently: Screenshots should be moved to the top of the content, right after the introductory text. Screenshots is the first thing a user wants to see while checking out an app, especially a Mac user.
Moreover, I’m a sucker for big headers, but well, this one kinda hurts my 13.3” Macbook. Only thing I can see when full screen is the humongous logo, the download badge and some text.
