That was also my reaction. However I started to wonder "Maybe it's just a experience-reinforced habit to mentally separate the content of the web and content of the other apps?" After all it's not the only possible paradigm. Computers used to be simple terminals and current web apps trend resembles that. Just think about Chrome OS. For me (a a person who has spent most of his life in local files, directories and applications realm) both Chrome OS and browser tabs mixed with other apps seem to be weird, unnatural and cumbersome. But for someone without the baggage of such experiences, this solution could actually appear more useful and logical.

Tabs are way more transitory. Their lifetime is pretty limited in that I will usually close them after I read its content. Apps are slightly more permanent. Also, on a more practical side, it is currently way faster to switch tabs because of those useful touch gestures in Chrome.

For me it's the opposite. Apps are transitory, tabs are long-lived.
