they can make a good commercial for this,
imagine this, the commercial starts off with a scene of a man walking into starbucks with the laptop and plugs it in (it is night time)
the dual display turns heads and gets attention, and showing off, the man tells everyone "watch this". He powers on the laptop and all of the lights in the starbucks dims and a street light outside of the building also dims. as the laptop loads windows vista.
Scene 2, the camera cuts away to a power station and warning alarms going off. dramatic music begins to play as all of the workers desperately run to the control room. Everyone scrambles to bring backup generators on line and redistribute power in the grid.
Scene 3, the camera cuts back to starbucks, one person in the crowd says "whoa... what happens if you try to play crysis"
Scene 4, the camera zooms out showing a view of earth from space and all of the lights across America going out. (during this scene the song "one" by Apocalyptica slowly fades in and the commercial ends
