Tablets and smartphones aren't PC's. It's ridiculous to compare those two against PC sales. It's even more ridiculous to claim that they'll replace the PC.
Guess it never crossed the survey takers minds that maybe PC sales are flat because everyone already has a damn PC. Just like XBox and PS3 console sales are flat. Whoever wants one already has one. And for regular users, you're only going to replace it once every 4-5 years if that.
I hate these kinds of articles (not TechSpot's fault - you see these types of articles in every news media outlet), because they're just plain dumb and are comparing oranges to tractors.
