Yes, tablets will kill off PCs just like television killed the radio. Oh wait.
I partly agree but a lot of people who I know have a smart phone and no computer. If it was not for smart phones they couldn't check facebook, email and browse the web. Which seems to be their only interest. So I am inclined to agree that smart phones are the main reason pc sales are down. Maybe more so then the plateau effect (everyone has a pc) because people replace their computers every 4-5 years and in 2007 we likely peaked now the numbers were getting from people buying replacements are down.
Well it made more sense in my head hope it came out right lol
