What makes me annoyed

What makes me annoyed when it comes to computers is the lack of understanding of operating systems that an ordinary person my age has, especially when asked what type of computer they have.

The popular responses I get are 'Gateway", "HP", "a gray/black/white one", and "a fast/slow one". I don't get it, don't all computers have some sort of message as it's starting up that shows the type of computer, company name, or anything?

Just had to get that complaint out...
