I think one potential answer to this is the ability for mobile/tablet apps to embed a browser inside the app. So you see this already with the twitter app on the ipad, when you click a link, it opens a browser in-app. The app makers don't reaaaally want you to leave, so the in-app browser is a nice compromise for them. And as a user, I like it. I don't necessarily need/want to leave the twitter app on my ipad. I just want to read the linked content real quick and jump back to the app. Works for me :)
Unfortunately, the browser experience can vary drastically depending on the app linking out. Plenty just dont at all. You see a link, but clicking doesn't do much but let you copy the text, if you're lucky to even have that. It's frustrating and makes me tend to avoid links in most all apps.
Take Flipboard, and otherwise beautiful app that is the gold standard for future blockbuster apps; when you decide to open a link to a full article you will get stuck inside an awkward hardy-useful piece of Safari. Even if you click out, you efffectively lose your place in the flow of what you were browsing. This is an example of bad integration from the browser. Don't even get me started on the apps that come with built-in browsers that feel like a toynrather than a tool.
I want to read the linked content not necessarily real quick and return back, and trust that the experience will be as good as a native app. In a perfect world all Apps would be web apps.
