Maybe I'm like the guy who said that no one will use a mouse, but I think for general use, computers topped out long ago. Now companies like Microsoft just add features to keep their oem partners selling hardware by grinding previous hardware to a halt.

By way of example, I installed arch with i3wm on a core 2 duo with an ssd, and it boots in less than 30 seconds, and is fine for general office use and web browsing.

Try running Windows 10 on that same build. It ain't happening.
