But why get the Steam Deck 2 when you could wait a little longer and get the Steam Deck 2 Episode 1?

That's a perfect way to get stuck in a loop of waiting for version n+1. Do you want to play current games on the go? Then SteamDeck 1 is a great option. The whole customer electronics market is designed to advertise "something better" to you so you keep upgrading, whatever choice you made before.

Valve said there will be no steam deck 2 for quite some time, so go for it
