The Steam Deck, Valve's portable game system that runs Steam OS and is capable of playing AAA games from Steam's vast library of games, is set to be released in mid to late 2022.

"Scalping" was coined in the late 19th century for individuals who would re-sell tickets, it is unclear if it was railroad tickets where it originated or theater tickets, usually for a profit. The term "taking a little off the top" when talking about money also refers to scalping. Ticket scalping originated in Amercan English, and the terminology is still used to this day, but not just for tickets.
