this firewall thingy which is reputed to protect you from bad stuff,
would also download and install the latest patches to protect against
browser exploits. If this is all run on a separate CPU it can also do
some pretty in-depth inspection and do things like block .exe
attachements in email.

This discussion started out with an assertion that that security
problem for general-purpose OS endpoints had been 'solved'. It in
fact has not been solved for any reasonable degree of solved - there
are basic layer-7 problems with the fundamentals such as HTTP (which
to most users is 'the Internet), and while there are various efforts
to attempt to mitigate these problems via the insertion of inspection/
removal by network devices, these efforts are in their infancy and
also introduce other complexities which are corollaries of the
canonical end-to-end principle (vs. the common misperception of what
the end-to-end principle actually encompasses).
