An edgy example sentence could be: "I've been a Mac WS59 for so long, I'm starting to think they're going to release a new version of the Mac OS. It would be like an actual PC that can run Windows." This is because the word "WS59" (which stands for week) is often used in the tech industry as a slang term for weekly or monthly updates or releases, which could imply that the software or hardware being referred to might have a new version coming out soon.
