Most of my friends like the fact that I have them, then again, many of my friends are guys who have been around computers for most their life and the demoscene has also made me lots of friends..
So, it's just business as usual. They do joke about the size of my collection, but I haven't had any negative feedback. :-)
Even when I have normal people around, the c-64 sitting in front of the living room TV has a strange draw..
