It is just what I noticed when I moved from the US to Japan (all my friends are British ex-pats now 🙂). So many of them are macusers. Like, really apple loving mac users.They even have .Mac!! It was not like this is the US. None of my friends used macs.
I have not noticed that at all, i go to England 2-3 times a year and i have not seen many people with macs. I always thought the Brits are more of a windows country (if you know what i mean), maybe its because were i have been unlucky.
I'd say around 30% of people where I live are Mac users. The student population helps, everyone had an iBook/PowerBook/MacBook at college and university. Relations are starting to buy them because of lack of viruses. Neighbours are getting them too.
This is all in the past few years mind. Before I got my first Mac I never spotted one in the wild! Maybe it's one of them things you don't see until you start looking?
I'm from the UK and I sometimes see 2 or 3 people with an Apple laptop if I'm in my local library, and I know 4 friends / acquaintances who have a Mac, but not too many people.
at my university there aren't many mac users (i know 12 including myself and my housemate who i converted) but at my gfs university there were only 2 windows users out of about 90 people that we knew. depends on the situation.
