Sort of unrelated, but it was my first thought: I sort of wish there was a cross platform store for wrapped web apps that could make them look sort of native-ish, that was widely adopted.

Not because this is actually something I want or think would be better than a browser, but simply because seems to be significantly easier to get users to pay for something that behaves like a native app, ie, turns up on their dock. I have a theory if you wrapped a web view and put it on the mac app store, the average user (ie one who has no idea what web view means) would pay more for it than the same product in a browser.
