Yeah, I think the Deck will reach lots of different audiences.
I also don't like people's absolutism. Like, it will be a Switch killer, it won't touch the Switch, Nintendo don't need to care, it will only reach a niche market.
In general I don't like absolutism like the above, like because the Deck can go anywhere. We don't know how it will do.
Yeah, there are no doubt lots of country were the majoority of people, like Norway, wouldn't have much money problem in buying a Deck, but the Deck might not be available there.
There are an increasing amount of people playing on PC here in Norway, many of my friends who were previously console only have moved on to PC and Valve are missing out on these potential customers in other ways than just Deck, like Index and previously the Steam Link and Steam controller.
