Typically, products are compared to similar products, for obvious reasons. For example, handhelds and home consoles aren't usually closely compared because they cater to different audiences, have different sales patterns, etc.. However, a more general route could be taken with such products: for example, determining which general gaming platform is most popular in the world. Deeper comparisons are usually restricted to those consoles in more direct competition (I.e. PS4 vs XboxO).
