Hey you, buy this laptop.
The stuff inside this box make the bumps and bleeps and binary go from soft quiet whispers to visible quality data. The stuff inside this box turns the invisible air waves into the news and weather, or streaming entertainment, or the big report your boss just emailed you. The stuff inside this box can even play the MP3s to your headphones, assuming you have all the wires plugged in correctly. And that's what a computer does. That's what a computer is.
