Thing is, you can get a second hand Switch for about $200-220 as it is. So I really don’t get it. Especially since every console has the ability to share to your phone or tablet already, and there are loads of controllers meant for phones or tablets that are less than $50.
I’m trying to defend here a product I don’t really believe in, so bear with me.
The portal lets you play PS5 games, in PS5-ish quality (-ish because it’s obviously not the same as a 4k TV). The best the switch can do is 7-year-old No Man’s Sky, with no multiplayer. Recent Pokémon and Zelda (first party Nintendo games) can’t even reach a constant 30 FPS in the whole of the game.
I don’t think graphics are THAT important, but I know there are people who think that. And in that case, the PS5+Portal is going to beat a standalone steam deck or a switch. If you have a beefy PC maybe a steam deck can stream in better quality, but if you’re in the PS5 ecosystem it’s the best quality handheld gaming you can achieve.
Would I buy it? Absolutely not. 80% of the fun with my steam deck is taking it places. The airport, the plane, a hotel on a business trip, my partner’s place, the dentist waiting room, the bus/train… All that’s missing with the Portal, but that doesn’t mean I can’t see a (niche) market for it.
