There are plenty of supposed Steam Deck killers available in the portable gaming space, from the Asus ROG Ally to the Lenovo Legion Go and all the Ayaneo and ONEXPLAYER devices in between. But none of them have managed to outright slay the dragon that is the mighty Steam Deck yet.
Yeah, reminds me of the original Gameboy. Weak hardware, terrible screen, great battery life, awesome first-party support, stupidly robust. Sold a hundred million or so. Up against the Game Gear and Atari Lynx, which although basically miniature consoles, had an unquenchable hunger for batteries and crap games. Complete turkeys. All of Nintendo’s other, very successful, handhelds continue the same idea; yes, a Switch is really underpowered compared to the newest Playstation, but that’s not it’s niche.
Yes; you can pack more powerful hardware into the space that a Deck, or a Switch, or even your phone, takes up. But is the amount of fun you get from that device increased in reasonable proportion to its increased cost?
