Awesome colors for a scroll down site . Incredible web design layout and color palette selected. I really like this homepage - whatever web designer created this would definitely have a job at Isadora Design.
DESIGN TRENDS 2013 - FLAT AND MINIMAL - There are lots of reasons to adopt a flat design, one of the most important is scalability. When designing for multiple devices it's important to consider ways to optimize the design.
An interesting (and pretty appealing, design-wise) look at typography. The information based on operating systems definitely represents the differences in style the OSes like to go for - Windows being traditional, Apple a bit trendier and Linux being all functionality. I'm typically not a fan of white text on black background, but in this case I think it's functional enough. The smaller text is tough to read - I'd vote for larger fonts across the board on this design.
