Your Primary Console History

[OdinHades]

Consoles: NES -> SNES -> N64 -> Gamecube -> PS3 -> PS4
Handhelds: Gameboy -> GBA -> N-Gage -> PSP -> PS Vita -> Switch -> Steam Deck

Since 1998: PC

I had a bunch of other consoles and handhelds over the years, but I didn't use them too much so I just counted devices that I really got the most out of. And yes, I really did use the N-Gage a whole lot. That thing was fantastic for its time.
As for the Steam Deck: I only have it for 4 weeks or something, but it already became my main gaming device. I'm absolutely in love with that thing. Although it is debatable if you want to count it as a handheld, a PC or both. I'd go for the latter.
