The root user is really a true admin id, as is the 'Administrator'
account on Windows. As far as I know all these have a 'protected'
kernel, but it is not a black and white issue it is the degree of
protection and as with any security measure it is only as strong as the
weakest part.

Unix came first, linux is built to be a 'sort-of' unix but is developing
beyond being a clone of some old unix system.

No, NT and 2000 shared a lot of code and had many security problems,
unix code was older, better tested and more secure

By default yes, but this can be changed by the admin-user and restricted
accounts set up, however that didn't happen often and most home users
didn't set a ordinary account up.

pretty much, most small computers were originally designed with a single
user and not much thought given to security

Ahh wrong, malware is ever changing, malware will attempt to 'leave the
account' we call it privilege escalation by exploiting any weakness in
the implementation of security measures. There are a lot of different
types of malware and some don't even bother with your user account they
target parts of the computers system such as the networking software or
communications systems (i.e. tcp/ip or rcp) to gain access to your
computer. In security there is never a 'can' or 'cannot' only 'has' and
'hasn't yet'
