I know many XP machines still chugging around peacefully without problems: No XPcalypse happened. This entirely fits my predictions.
XP was a (had become) a mature operating system. I abhor the fetish of "newer is better" that reigns in our industry.
What I think of Luxleaks
From VM creation and installation from SP3 OEM ISO to fully patched in 1 hour and 30 minutes. Not all that shabby.
It also indicates that XP will most likely die totally when they turn off the activation servers. I don't think they'll hand out the promised "no activation patch", ever. (Well, I always heard they'd promised such a thing, it might simply be legend.)
