Examples of 10mm wide angle to 17mm
You can quite clearly see the different perspective between 10mm and 17mm in the Anthony Ryans shop and the bookshop interior (last shot).

I haven't used it a great amount for urban shots, but when I have it always pleases me. It gives you the opportunity to tweak the perspective and do some cropping which I have found handy.
When I decided to sell 7 of my 9 lenses to fund a second brand of camera, it never crossed my mind to part with the 10-20. No prizes for guessing what the first 3rd party lens I picked up for my new brand of camera was.

Sorry about the quality, I was just messing around with these on
a very dull day whilst waiting for some friends.

I presume there's many other like me that would like to see how much more you actually capture with a wide angle. So here are some photos comparing 10mm with 17mm.
My thoughts are it's a 'nice to have' lens but I don't know how much I'd use it.
Cheers,
