Hi,

Lots of chat here now! :)

if YOU prefer "friendly" URLs for whatever reasons you have found sound, then you should feel free to use whatever add-on you find will be the most sound one to use to provide this feature.. However, much of what you have assumed and posted about why friendly URLs are a better choice is not based fully in facts.
I think it goes without saying that, on the balance of things, friendly URIs are the better choice.. sites look better with human-readable URIs and there are no negatives to having them. None. (I don't consider using more server resources to be "negative" but a "sensible business/technical decision").

Few probably need product urls for printed material and nobody really remembers even a re-written url; hard enough just to remember the domain.
I disagree, I think having URIs like "/summer" is something well worth having - in this case a URI for a site showcasing the summer specials, useful for printing on bill boards, bus stops etc. I agree that not many may "need" this but I do think it's something some sites do need, more likely to be larger stores with physical, real-life advertising.

Anyway.. I'm biased of course so I would say all of that ;)

Regardless, /about-us just looks so much better than /index.php?main_page=page&id=3 so I think all sites should use Ceon URI Mapping. :)

Have a good afternoon!

All the best...
