@[deleted] WetGeek It seems to me that the minimum requirements and average user requirements might be of interest to users of low-end hardware and older hardware, as well as, of course, to power users planning to run VM's, particularly power users who forgo dynamic VM's in favor of static VM's, and users who dual-boot.
Minimum requirements establish a baseline for a casual use. Average user requirements establish a baseline for more normal use.
Assuming that 25 GB is the right threshold for minimum requirements, a casual user could use Solus on a computer with a 32 GB eMMC drive, typical of older Chromebooks and older low-end Windows laptops. However, assuming that 50-60 GB is the right threshold for an average user, that would not be the case, although low-end and older laptops with 64 GB eMMC drives should work out okay.
I realize that neither threshold is relevant to users of new hardware. Chromebooks now come with 64 GB or higher SSD's, sufficient for the average user, and Windows laptops sport 128 GB as a minimum, with 500 GB becoming the norm, both of which exceed anything likely to be needed by an average user. But so long as Linux keeps up the "Brings older and low-end computers to life again ... " meme, realistic system requirements remain important to casual and average users.
Along those lines, I wonder if it is time to up the ante on RAM for average users, as well. 4 GB is fine as a minimum requirement and for casual users, but 8 GB might be more realistic for users who have several applications open at the same time or use applications that are at all memory intensive. Again, it is probably a moot issue for newer hardware, because it is increasingly difficult to find anything other than a Chromebook or very low-end Windows laptop that has 4 GB RAM.
Power users can take care of themselves, as you have both pointed out.
