Perhaps if you only think of persistence as being connected.
It doesn't have
to be just about being connected. Persistence is/should be
also about
time-shifting and being in sync, with respect to local
storage, file system,
other apps, peripherals, etc.
For instance, I am currently re-designing a fairly elaborate
application
process that can take some time to complete. During that
process the user
will likely need to consult his records, maybe other people,
upload/download
documents, etc. I want this process to be interruptible,
for all kinds of
UX reasons. This is a classic pattern (not fully solved by
server-side or
cookie implementations) that, for instance, Adobe has
attempted to solve by
way of PDF forms. Since the solution I'm interested in is
web browser based,
a persistence framework would have helped enormously to sync
up the
aforementioned interrupted completion process.

No need to wonder: we are. 
Of course, Adobe would beg to differ, as their upcoming
Apollo platform
essentially layers an OS-agnostic platform on multiple
OSes.

Well, not Watson since it's been dead (thanks, Sun) for a
couple of years.
But I do share your outlook.
In fact, iPhone+WebKit combo is a shining example of a
device-specific great
UI looking for platform agnostic data to connect everywhere.
The notion of
"loading apps" is so pre-iPhone.
