Knowing a few people running lubuntu doesn't make it an average. That is just a personal bias.

I never said it did, I was just trying to explain/give examples that Linux isn't just for tech professionals.

From experience almost all the computers I serviced over the last few years were either bought at Walmart, Best buy or Amazon

If that means that they didn't even look at the manufacturer site, that surprises me, I've found often that some stats are just left out of product descriptions, which to be fair is the same on manufacturer sites (I've never found SSD speeds for instance) but nonetheless there's usually a lot more info than looking at the label in a store. Even my less tech savvy relatives managed to figure that out, but then did ask me about the relevance of some stats.
