hardware requirements
If that doesn't change, the year of Linux on the desktop may be upon us, brought by the most unlikely chain of events to boot.
Many serviceable machines are 7-10 years old, and many people in first world countries are having trouble to upgrade, let alone the third world. You find TPM 1.2 in some, most won't have anything.
Hell, even new machines won't make it. The machine I bought a couple of months ago - 11th Gen Core i5 - does not have TPM 2.0, thus incompatible. I can get a module, but I assume these are probably overpriced by now, just like everything else.
