What...bring it on...consumers benefit.
Mobile devices have two major concerns that desktops don’t (or at least not nearly to the same degree). One is energy consumption and the second is heat dissipation. Desktops aren’t being held, they are surrounded by multiple fans moving air in multiple directions, and they don’t have to be held. They are also plugged in, so battery life isn’t a concern.
That's what we thought last time, and then we ended up with grossly inefficient, power-sucking chips.
