This is going to sound insane, but probably the Nintendo Switch (or maybe the capture card I got after that). That ended up kickstarting my YouTube channel and internet presence a ton, including my most popular video, and launched my community on the side. That community ended up introducing me to many of my closest friends, getting me various interviews with project leaders and figures in the gaming world, and (due to the site/channel/community being mentioned on my CV at one point), likely got me at least one of my tech jobs.
