Rexexp on part of a string

Hi Aaron
I'm writing privately rather than cluttering the list.
I like your answer here, as it illustrates two things.  Problems should be 
broken up into the  logical things trying to be achieved, as its simpler to 
test, understand in the long run, and probably more reliable because of doing 
so.

I forgot to ask you as edin.pm about the laptops you have. You want me to pop 
up and look at them  ?

Can you remind me again why you don't rate PHP as a programming language ?
