Back in February, before the world changed, I went with my son on various applicant days for physics courses at various UK universities. One was showing us a particularly specialised bit of kit in one of the labs, and I spotted that several of the PCs connected to it had the XP screensaver. Nobody could get the control software to run on anything else, apparently. Worried me somewhat about their technnical capabilities...
And then in lockdown, I was tiding my office prior to redecorating it. Found my ancient Eee 904HD netbook - the battery was dead, but on plugging it in to the mains, XP booted straight away. Or rather incredibly slowly, but without issue. Hadn't used it for 10 years, according to file dates. No idea what to do with it.
