For what it's worth, I realized after I wrote that original comment that I have a (rather powerful) desktop in my basement that I stopped using several months ago (really, about 2-3 years ago my usage dropped off substantially). I had just done a large hardware upgrade, re-activated Windows 7 Ultimate and ... a project heated up which caused me to not use it for almost six months, the PSU started to flake out, causing it to be unstable under moderate load (with PSU testing A-OK) resulting in another 6-months of reluctant, infrequent, use which became so infrequent that the last time I touched the machine it was to unplug the Ethernet cable as a precaution against accidentally using a two-year out-of-date and out-of-support OS to check my e-mail.
I intended on upgrading it to Windows 10 but fell into one of the worst projects of my life that put it off for 3 months, I had already grown accustomed to using a new laptop, loaded with Tumbleweed which matched my work laptop and just never got around to it.
One of the de-motivators to that was expecting that I'd be forking out money for the upgrade. That's disappeared, now, and I had already planned on finding all of that out this weekend/doing it because I'm at the point where -- though there are one or two things that there is no Linux version of my preferred app, and either my muscle memory in that app is so strong that using the alternative is *tedius as hell, especially for a rare need*, is so bad that calling it an *alternative* is highly misleading. Plus, I'm sitting on a 2070 that I acquired from family near MSRP to add to its existing 1070s and I'm pretty sure my kids will kill me if I wait any longer.
