I think there is a chance that smaller and mini desktops will never get a huge amount of users like mini consoles like the Playstation TV/Vita TV, and the Ouya which both never became very popular like the PS3, PS4 Xbox One, and Xbox 360.
I think people still prefer a bigger more powerful desktop and laptop with more RAM, a faster CPU, more storage, a faster video card, and more features to play HD and 4K video and games on their HD and 4K monitors.
A mini-desktop and mini-laptop usually does not have the speed to do as many things as a Full size Gaming Desktop, and laptop, or even an average sized home computer with 6GB of RAM, and faster CPU like Intel Core i5.
