The problem with the steam deck... [it's] more annoying and embarrassing to lug around in it's bulky case... I saw an adult man in a kitty-eared hat trying to play a game on a Steam Deck in an airport once, and the only thought in my hand (sic) was "Dang, I'm glad I left mine at home for this trip."
So, maybe not many Steam Deck buyers would be willing to buy another one, regardless of how it performs. I know I for one wouldn't. Their effort would be much better applied toward shrinking their current platform down to a usable size, preferably with either a bigger screen or much smaller bezels.
