I bought a $5 Steam Controller 7 years ago and forgot it existed. Now it's my new living room sidekick

This week, Valve released a $99 Steam Controller the general public was so excited to have that it sold out in 30 minutes, temporarily tanking its service in the process. It was the best selling product on Steam despite zero active players (dead device?). Not to brag about spending too much money on a controller I don't strictly need, but I got one.

Valve says it didn't expect the gamepad to sell out so quickly, and I can understand why: The last time the company put itself out there with a dual touchpad input device...
