I really don't get why they are throwing away a nice, clean, smooth interface to embrace a new big "touchy" UI even on the browser and the desktop.
I understand it's important to implement a native App for smartphones and tablets, but I do not like at all the trend to transform the desktop UI with big buttons, huge padding everywhere etc. (GMail style).
The whole thing looks like something out of the 80s. Like a bad VCR science video that you know still gets played when it comes time for the kids to learn about atoms.
