Wow!  I like it!  Especially the new navigational system and the "purchases" link with the expandable views for each order.  I don't have any problems with any of the colors as so many other have reported, although I do have very high end large monitors.

The only thing that I don't like is that the thumbnails for products are two different sizes.  I'm assuming this is to get more money out of vendors by charging a higher price for them to get a larger thumnail on the product list pages.  The problem is, when you have a row of 4 products and one or two of the thumbnails are larger, it's distracting and a little annoying.  I want to scan across the row of products but my eye is natually drawn to the larger thumbnails making it harder to scan the products quickly to see if there is something new I like in the smaller thumbnails.

Other than that, I love the update.
