Take one standard Mac mini. Change out the power supply with that of a laptop (power and battery). Connect it to a LCD digital photo frame and add a compact usb keyboard.
It’s tiny. Shouldn’t weigh more than your average laptop and may even be cheaper than an entry level Macbook.
I got the idea when I saw some LCD digital photo frames in Media Markt the other day. They looked really stylish. Then in the MAC section I saw a MAC mini for the first time ever. I thought, gee they’re really tiny.
Let me know if you have a better name or anyone actually builds one….. (Could happen).
