I'm no UI designer, so I was mostly just getting ideas from the Android
Gmail app, which I like a lot. However, using a page stack, at least on
the phone, makes the most sense in my opinion, because it conveys the
hierarchy of the email layout well:
acco...@server.com
Inbox
Test Message
2nd Message
Drafts
Draft Message
Sent
...
Having a separate tab and using the flat navigation structure doesn't
make sense. According to the design documentation, "The user moves
between main views of functionality of equal importance." An list of
emails and an email don't seem to be equal in importance.
In the case of a tablet/desktop version, I would suggest doing something
like the Ubuntu UI Toolkit Gallery app does, and have a side bar with a
list of messages, and then a main content view.

Why is it a crutch? According to the design documentation, a deep
navigation structure should be used to convey a hierarchy, and is one of
the three main navigation structures.

I've only been following the last couple emails, but I do think that
since the page stack is one of the three main navigation structures, the
location and implementation of a back action is quite important.
