Is it any wonder

That people are confused about the difference between RAM and disk space when one of the largest UK computer retailers puts out garbage like this in a mail shot.
 
Here is a tip form PC World's "The Tech Guys"
 
How can an external hard drive free up space on my computer? 
 
If your computer's running low on memory, an external hard drive can give you extra space. Simply plug it in to your PC and start transferring your photos, videos, music and any files you like. To access the files again, just go to My Computer and open your hard drive's folder.

 
An old friend of mine works as a Tech Guy for the local PC World.
 
Reassuringly, he's one of the good guys who has nearly lost his job (twice) for cutting through the bull with customers. He'll also gladly offer straightforward advice that means customers don't need to bring their PC's into PCW and get charged the earth for it - I believe one particular example of this earned him his 'written' warning.
 
So go figure - he fulfils his job description as a 'Tech Guy' (at which he is very good BTW) by giving technical support to PCW customers and gets a written warning for it; instead of blinding the customer with science thereby getting PCW an inflated and unnecessary fee for work the customer could do themselves if properly informed.
 
Sadly, he's as rare as hen's teeth I'm lead to believe. Moreover, it seems that a lot of the so-called 'Tech Guys' are only there to deal with exchanges and refunds as well as offering product advice (usually geared towards the more expensive, as opposed to the most appropriate, goods).
 
 
 

 I was sure the OP was going to mention Mooch (or at least Bapu)
