I wouldn't call any console I own a disappointment, even the Wii U had several games I loved and put too many hours into. But the system I ended up playing the least was the Steam Deck. It's just too bulky to feel like a proper portable, not nearly as cozy as the Nintendo handhelds I grew up on. I get some use taking it to FGC events as a monitorless setup (and I will be bringing it to Combo Breaker 2026 next week), but that's kinda all I ended up using it for.

I still don't regret buying it as the most important thing to happen to Linux gaming, but it was a system I bought to have more than to use. I later bought a Miyoo Mini Plus and ended up putting far more hours into that than I ever did the Deck. If anyone ever gets SteamOS running on a device in that size form factor, they'll get my entire bank account.
