As has been pointed out in the replies about 30 times already, PostPC doesn't mean the PC is dead, it only means that the PC market is mature and innovation slows way down as everyone focuses on newer more dynamic markets. The fact that people feel no need to upgrade their PCs anymore yet they are still rushing out to buy the new iPad is symptomatic of that. Surely I'll buy a new PC in the future to replace my old one, but I don't expect my sister or dad to do the same.

I once had a workmate in 1999 whose sentiment was similar to your post, just focusing on a different device. We got into an argument about whether the desktop PC market was over or not. He didn't really believe that laptops were really more than niche devices, they were too slow, displays were too small, that most people would use desktop PCs for decades to come. That you could never do more than surf the web on it, you couldn't hack serious code with it.

That tablets are for consumption only...really? Diagramming (e.g., OmniGraffle), vector graphic production, sketching, mixing and producing music, editing images, updating a spreadsheet...why not? Many are using tablets for production already. Every year someone says iPad can't do X, the next year someone releases something that does X and it actually doesn't suck.

I often use my iPad 2 in bed (~1 foot distance), the screen is really close and I can see the pixels. The new iPad is absolutely frigging amazing, I'll never look at my crappy DELL/HP monitors at work in a positive way again (yes, I can see the pixels!). Why have we been stuck at the same crappy 1920x1200 pixel resolution for at least 5 years now? Could it be that no one care about innovating in the PC market because they can't make any money? That a 10" iPad has a higher resolution than my 24" PC monitor is totally Post PC.
