In general, copying one updated program rather than
all of them is not optimal, as I guess you realise.
Incidentally, what I periodically do is copy the entire c:\ado folder from 
my desktop to my laptop.  Partly I do this because, for some unknown 
reason, -findit- and other Internet-related commands do not work on my 
laptop.  But, it is also a way of keeping your machines in sync so you have 
the same programs installed on each.  You do need to be careful that 
profile.do and possibly other customized routines will work ok on both 
machines.
