What exactly do you mean by 'the file types system'? A preferred
applications system doesn't allow the user to specify a different app for
one specific file of a certain type, and I think that should remain
possible.
So far, AFAIK, the preferred applications system is a very simple way to
complement the MIME system associating a choice number of applications
(web browser, text editor) to a small number of file types (web
pages/URIs, text files). I think it should be expanded, but not to the
point of replacing the MIME system. See below.
1) Not "infinitely extendable" like a List would be.
Yes, this leads me to conclude that a Preferred Apps system is
unsustainable in the long run.
Havoc made a good suggestion in another post in this thread:

But IMHO Seth is 1000% right in noting that 99% of times the user will
try to associate an application to a file type when he clicks on an icon
and finds that there's no default application set to open that file (or
he doesn't like the default application, e.g. Quanta Gold for HTML
files). The file type association thing should work both ways:
1. there should be a centralised system where you (= possibly the system
administrator) have all the power of the MIME system and associate files
to applications via file types and sub-types;
2. OTOH, it should be fairly easy for an user doing the following:
a) associate a till now unrecognized file type to an application;
b) change the default application for a file type.
I think that Seth's proposal fits very well for 2., all the more so as
the central MIME system currently doesn't work very well and will
probably be rewritten to be a common standard between desktop
environments (at least this is what I understood and hope would happen :)
Going the other way round, i.e. moving the burden of the file type
system to the application properties, is not very intuitive for the
user: you have files under your eyes all the time, the same is not true
for applications.
