Also I'm kinda curious: Why would spend twice as much to buy an Intel Mac PC if they're just running linux? I'd buy a regular PC for 1/2 to 2/3rd the cost.
I looked for a silent small footprint linux pc. I was unable to find one. That's why I bought a Mac Mini. It runs Linux flawlessly... and silently thanks to the fanless design and SSD.
People wanting an HD screen on a laptop might also have to buy Apple hardware even though they plan to use only Linux.
