@ Cammy & asm1 - being different is nothing to ever be ashamed or embarassed about - I've got a scar across my face from being stabbed when I was younger.
Sometimes people give me a funny look or double take or whatever. It used to bother me but as I've gotten older my attitude has changed to not really caring what might go through other people's heads when they first meet me.
If everyone was the same the world would be a very dull place so my advice is to keep smiling, do what you want to do, feel proud and anyone who doesn't like it well f*ck them!
As to what my friends think of my retro computer habit well they used to take the piss a bit and think I was weird but some of them have seen how I've been getting on with my coding and I've had a few more "wow - you did that? Cool." reactions recently.
Anyway, I love keeping it retro so who cares about anyone else right?
