Moonlight

I own an Android phone, but I use it mostly for texts, emails, and reading the Times, so I can't say I would ever think of it in the same way I would think of, say, a Beethoven piano sonata. Regardless, this commercial is very cool. It's not just that they bothered to rebuild a piano with all the strings tuned to middle C, which is nifty. It's also that the rhythmic drive of Beethoven's masterpiece is compelling and exciting even when played in monotone. Of course your mind's ear is filling in the arpeggios...
