Hmmm. Lies, damn lies and statistics! I studied statistics at school and know there are many ways to present information. I think it might be true that people who use Macs will tend to be younger, more urban types, but that doesn’t mean that PC users can be categorised as being older and rural. If you agree that people of all ages use PCs, then the average would be mid-30s, I guess. There may well be more young, urban people using PCs than Macs, but the “average” statistic won’t show this up.

So I think the stats tell you some useful info about (the smaller sample set of) Mac users but the rest probably just reflects the general population rather than PC users in particular.

Did you know that 38.6% of statistics are completely made up? ;-)
