On the topic of the PC plummet, here’s Matt Rosoff:
You can hash the numbers any way you like, but the trends are clear. The PC market is getting crushed by tablets. In fact, I think we’ve reached a tipping point that will mean the near-total collapse of the consumer PC market within three years. By mid-2016, consumer PC sales will be less than half of where they are today. Probably way less.
A few years ago, such a claim would have sounded beyond outrageous. It doesn’t anymore.
Personal computers will be a relatively expensive high-end product that people buy every five or seven or 10 years, when their old one breaks or becomes absolutely unusable. Sort of like big-screen TVs. Some of those PCs will be notebooks, but people won’t use them portably as much as moving them from room to room around the house.
For everything else, people will buy tablets. The second (and third, and fourth) computer in every house will be a tablet. Every kid’s first computer (after their smartphone) will be a tablet. If you take a computer on vacation, it will be a tablet. Eventually, the computer most of us take on work trips will probably be a tablet, too. (Whether it runs Windows, OS X, Android, iOS, or something else — that remains to be seen.)
Cue the trollish, angry, pigheaded, and short-sighted comments! Oh wait, I don’t have comments :)
