That's precisely what you just did above. Also, mice are a personal taste thing, so why the hell would I (or anyone else) discuss things that don't apply to themselves? What use would it be talking about what kind of mouse would apply to the bum that lives on the street outside?
Stating the praises of cheap mice/keyboards as some kind of factual data is stupid, as is disregarding the (very real) benefit that can be achieved with a slighter higher value product
EDIT: A really good example of this is buckling spring keyboards vs. rubber domes. Rubber domes are cheap, and will last some time - buckling springs are expensive, offer better tactile feedback, and will literally last decades.

Reliable is quite different from high quality, ergonomically friendly and long-lasting.
