"We can rebuild it! Smaller!, Better!, Portable!" - Ben Heckendorn quote.
Can we rebuild it smaller, better, and portable??? That's my Idea! A PS1 that uses a smaller powersupply that doesn't give off much heat, a different / newer motor that can hold heat better, and as a portable system with that can have the memory card slots 2 more outputs for controllers at least and the original composite out port which depending on the cords you use also acts as a component (old school HD) port.
