This was from 2021, so prior to the Steam Deck... that was really their break-out moment, I think, with regards to hardware. The Steam Link and Steam Controller were neat but didn't really capture their respective markets, and the Index was widely considered one of the best VR headsets on the market but that's a relatively small market, and it priced out all but the enthusiast tier consumers. The Steam Deck on the other hand had mass appeal and basically ushered in a golden age of handheld PC gaming... not to mention the immense hype around their recent hardware announcements. Could be that their hardware team is making more now.
