Mac users tend to clump together and be rather unaware of the larger world as they worship Steve Jobs - ignoring both his and Apple's many failures.
A funny - maybe 6 years ago I was having lunch in a Thai restaurant. A group of about 8 guys walked in, all dressed "casual chic". I noticed a rather odd uniformity of style and personal appearance and said to myself, "Mac users". Sure enough, they sat down at a nearby table and immediately started talking about Macs - for the whole lunch.
