Whilst standing in the back room at the ballet school that my daughter Sophie goes to, I had an interesting conversation. I was wearing my Ubuntu Hardy Heron T-shirt which I got from the Canonical Online Store.

One of the other parents (a mum) said to me "That's a nice T-shirt, where did you get it? Is it a Paul Smith?". This made me chuckle a little. I had to reply "No, it's not, it's 'just a promotional T-shirt to do with a product I use'". She was surprised. So was I.
There's something to be said for geek-wear that doesn't scream "I AM A GEEK T-SHIRT".
Don't forget that every month on the Ubuntu UK Podcast we are giving away discount codes for the Canonical store as competition prizes!
Update My family all just descended on my house for a Barbeque. My brother just said "Hey, nice t-shirt" :)
