@Mundon Wow, we got ours around the same time! I've paid for it at the end of August and received it early September.
A few months ago, it was possible to check playtime for each platform via steamdb.info but Valve made some API changes so it's no longer possible; last time I've checked I had a total of 300+ hours on #SteamDeck (in less than a year) compared to 1000h on my Windows desktop since 2019.
I totally get the "throwing controller" feeling, it made me a calmer gamer haha 😆
