The difference is we're talking about a product category that has penetrated culture in a meaningful way, rather than tech that is meaningful to people with specialized knowledge. iPhone was ground zero for the general public consciousness in this space, it made this product category mainstream. It's silly to argue otherwise. Also variable valve timing was plastered on trunks of cars in the 80s so folks of a certain age should recognize the term, and Linux as a term seems pervasive enough that most people should at least have heard of it; they likely have no idea what those terms actually mean though.
