I like how ZDNet decided to combine the worst parts of a lightbox and a gallery to make this a torturous exercise in page loading and mouse dodging.
What a half-assed fail.
same old windows ugly and outdated UI it depresses me to see those boring windows gray buttons
What you're looking at is the "Classic" UI theme. Windows has supported themes since XP (released in 2001), and as of Vista there is also an optional desktop compositor that uses GPU texturing and shaders for transparency and blur effects.
But this is a preview of Exchange Server 2010. Why exactly would you want GPU compositing or gradient buttons on a server?
what would you rather have? red on blue? animations?
