Pretty much daily.
I work from home, and my work computer and personal rig share a desk - by the end of the work day, sitting in the same chair at the same desk to stare at another screen started feeling like a chore and I had all but quit gaming.
The Deck has changed that. Not only am I loving gaming again, but I've found myself playing genres I never would have on my PC (things like Vampire Survivors just feel great on it, but I had no interest in them on my PC)
Going to be interesting to see how much more active it gets in the coming weeks
