If there was one highlight from last night's CES keynote we'd have to say Bill Gates and Robbie Bach's Guitar Hero III-off was pretty entertaining. Actually, neither actually played the game as they each had their own "ringer" to play for them, but that's half the fun. We'll agree that it's a bit scripted, a bit awkward at times and a tad of a stretch, but seeing Bill Gates bringing Slash on stage and watching the over-production of it all is simply priceless. Not to mention the fact that we have Les Paul faceplate envy and hope Microsoft hooks us up with the one they used on stage. Relax, watch and enjoy.
