Does your manicurist have you dip your fingers in Palmolive to soften the cuticles? Does your restaurant serve you Sanka with flavor crystals? Is that Pepsi or Coke you're drinking?
Microsoft shows it can be just as tricksy. Is that a new, incredible OS you're using or is it Vista?
Gizmodo has a good take on this "experiment". Basically, Vista is fine for the average user when everything works. But if you have an older PC that uses older drivers, then good luck figuring out what to do when things don't work.
