"There will never be one winner."

There will, however, be many losers, and PCs are going to be one of those losers. The form factor won't die, but the philosophy and freedom will die. It is inevitable, given the priorities people have and the money to be made.

If things continue going the way they are going, the only computers that will give users the freedom to do what we can do now will be locked away in research labs, available only to the lucky few who can land jobs in such places. These computers will be so expensive that only people who are doing funded research will be able to afford them. The next best thing will be computers targeted at developers (perhaps "debug" computers), which will be too expensive for most people to consider buying them but (hopefully) inexpensive enough for hackers to get their hands on them; these will still be loaded with restrictions, but at least the user will be able to write and run code and use a debugger. The only computers that will be anywhere near the price point that most people will consider paying will be those that are restricted to running software that was signed by some large corporation (i.e. only approved programs), with only the macro systems for a few "professional" programs (priced beyond what most people can afford) being available for user programming.

Why would software or hardware companies want it any other way? The next "big thing" will have to be filtered through the app store system, and the little startup that makes that software will be bought out before they can overtake the established players. The big media companies will form partnerships with the companies that control app stores (or just mergers, so that the whole stack is controlled by the same entity) that will be immensely profitable. ESPN will require all of Dell's customers to buy the ESPN app, without the option to get a refund or to remove it, and any company that does not take that deal will be barred from having the ESPN app on any of their products. Governments will love it -- no more uncontrolled cryptography, no more Wikileaks, CALEA-style laws for computers, and a chance to spot political movements before they take hold.

"Free flow of information and low friction information searching certainly is one use case where the web is so so much better than apps can ever be in their current form"

You can just pay $1/mo. for a search engine app, right? It will have an integrated web browser/hook into the installed browser. Not much different from having a Bloomberg terminal on your desk, except that it would be terrible for consumers (but profitable for businesses).

"Lastly "apps" have always existed. Nintendo games..."

Gary McGraw has pushed the idea that the security systems seen in video games ultimately become the security systems on all consumer computing devices. At one time, this app store model was something only video game consoles had; now we see it on tablets, and soon we will see it in other form factors. Video game consoles have highly expensive, hard-to-buy "debug" versions and developer systems; is there any reason to think that such a system could not come to exist for other consumer electronics?
