It seems like even Microsoft's marketing department knows a thing or two about nerdy UI stuff, as a recent survey that offers copies of Vista Beta on CD asks what the fancy new 'let's make everything 50% transparent because transparency is teh r0x0r' effects in Vista are called. Wouldn't you know - Aqua is one of the multiple answers! Right up there along with 'Aero' (the correct choice) and 'Zero' (funny how they rhyme). I would honestly love to see the stats on these test results.
Fortunately, Microsoft also allows Vista beta hopefuls to share how the four-years-late OS truly makes them feel with another question: "Windows Vista brings _____ to your world" has three options: Confusion, Creativity and Clarity (nevermind the large Vista banner at the top of the survey page - pictured). Be careful how you answer kids; you do want that copy of the clarifying (hint hint) Windows Vista beta, right?
