So 53.1 billion was still spenty on PC silicon, right?
Yep.
Phones have become a status symbol. PCs sit on your desk at home, so it's hard to use a sweet PC to look cool in front of other people. Also, women never really took to the home PC the way men (teenage, young-adult men) have, but women do like thier phones.
I bought my wife a HTC EVO. It's nice. She really likes it. I still can't stand to search the web on a phone. It's good in a pinch if I'm on the road, but if I'm at home I'll set my phone down and go upstairs to my PC if I want to get on the internet.
So in short, the smart phone will take over because people think they look cool when they have one and smartphones are women inclusive. Yay for smartphones. Meanwhile I still HIGHLY prefer my PC to my smartphone.
There are a number of reasons why the smartphone is surpassing the pc. I guess looking cool for some people is probably one of them.
As for your own preference... Nobody is claiming that everyone will suddenly decide a 4 inch screen and on screen keyboard is better than a 22 inch screen and full size keyboard. I am saying future phones will be able to use that same 22 inch screen and full size keyboard.
The Evo 4G was not made for that. The community did a great job of adding this functionality to the Evo though. See here:

Keep in mind, that video is from several months ago. It looks and works way better than that now with the latest software. There are other launchers (interfaces) too that make it look better.
The newer smartphones have all of this built in though and are actually made to be used in this fashion. The Evo 3D, for example, can be plugged into a TV and mirrored like that right out of the box without installing anything or changing any settings. And it has a higher resolution so it looks better. And it's twice as fast too (although speed wasn't a problem on the Evo 4G). Plus, it comes with Polaris Office, and the Docs app.
So the claim in this thread is not that people will suddenly decide a 4 inch screen and onscreen keyboard is better. Rather, the claim is that once everyone has a smartphone, and the smartphone can duplicate the functionality of their home pc, people will start using their smartphone like a pc. And when that happens, people will stop using their pc.
