It’s an improvement on the last design, which is good thing to see. I’m still not convinced it reflects the quality of the OS itself though.
It’s hard to put my finger on, but it somehow looks dated despite the fact it’s new. I’m also not convinced by the ‘floatyness’ of the content on the homepage (sub pages appear to be nicely aligned and less floaty). But, don’t get me wrong, it’s good work and a definite improvement.
