The PC is dead! Oh wait, the tablet is dead!
No, no, wait, the post-PC PC is too PC!
No, I’ve got it, the post-tablet is post-dead!
No, no, the revenant tablets are rising up and going all Cthulhu on our collective asses!
Ridiculous pronouncements and sloganeering aside, neither the PC nor the tablet is dead; this is merely what maturing markets looks like.
It took the PC market ~30 years to mature. It took the tablet market around five.
We’ll see continued reduced market share for the PC to the tune of probably 20% fewer sold in 2024 as compared to now, and tablet sales will stabilize a bit higher than they are now (in the Western world).
If you basically ignore what nearly all tech pundits claim and predict, wisdom can be found.
If the PC really were dead, and more specifically replaced by mobile devices, then the replacement of Flash by HTML5 (which I hope to see, because open source) would be a lot further along by now.
