I hear what you're saying and you got a point because doing only the kind of analysis I did can sometimes be misleading; however, I think looking at relative growth instead of absolute is more informative in this case because it better illustrates a growth trend. The number of Linux PCs running Steam more than tripled in 5 years. I think that that is worth highlighting and I wanted to point it out to balance what the article had to say about Linux growth, which I really thought was minimizing how remarkable that growth is.
