Amazon.com redesign

I just wish they'd make it fixed width. The site's barren on my wide monitor.
Here's a shot: http://imgur.com/FULDM
Amazon uses "feature flags" which allow them to roll out new features or design changes incrementally (i.e. to a random x% of visitors).
I actually prefer the "classic" Amazon look, because I prefer having the additional color. I'm so used to the old design, the new one looks too white to me.
I'm not sure about the menu redesign. Not having it show is a little cleaner. I use it a fair bit, but I may be strange. Having it show up if my browser is wide enough is a smart idea, but the drop shadow make it looks like a menu popped up because of my cursor. Since my cursor is somewhere else on the page, it triggers sort of a "why is that stuck open" note in my mind.
Once you get off the home page, everything looks basically the same as always except for the change to white.
