While we know that Valve have said repeatedly not to expect a faster Steam Deck 2 any time soon, it appears they may still be doing some kind of refreshed Steam Deck.
I find that placing the Steam Deck inside the case for a few hours recharges the smell for a few minutes, as my unit no longer smells like new. It's like a drug, it now lasts so little and is just a little sliver of the wonderful feeling it was the first time.
