You're absolutely right, it's a shame that Palm is essentially dead walking. Google's ChromeOS will be picking up the torch of "everything's a tab" when it hopefully ships later this year. Apple hasn't yet backed themselves into a corner where they can't rip it off, but to do it right would require them to not be their usual bossy selves. In an ideal card-based iPhone world, apps would have the option of being document-centric and be able to register for URL-handlers and file-types (both just like on OS X). Unfortunately the new Apple would probably never let them become the default in place of built-in apps (no registering http:// http://, no owning image/jpeg, etc.). I think they'll have to do it eventually, but it might take a while. They might try to let the new multitasking API percolate in the wild first, and develop their replacement for the hierarchical filesystem UI and maybe OTA syncing in the meantime.
