All in all switching to this doesn't really have many benefits that a casual is gonna care about. Even the greatest not paying for online has drawbacks. If you're a casual still better off buying a PlayStation.

Being able to access 99% of games for a 1/4 of the price is the number 1 thing casuals care about. Do your research on the epidemic that happened during Christmas when parents were buying emulator consoles for their children, and the consoles had hacked porn games on them. They spend 200 without even thinking about it or doing any research. Just so their child could plug and play old games.
I’ve been looking to purchase a mini gaming. PC so I can play my emulated PS1, PS2 and GameCube games on the big screen and possibly get into Steam as well. Depending on how much this costs the price might be overkill and I also think that controller looks hideous.

Exactly. This is the exact type of customer they are going to appeal to. I never owned a gaming PC in my life and I'm thinking about switching to this (XBOX owner). I can just download the XBOX APP and I'm good.
So they gotta appeal to the console gamers who been on the fence about making the jump to PC

Exactly right. When you really think about it, that was the original pitch for the XBOX.
Steam made their system base of the average specs of their users. This device will sell like hot cakes because majority of their user base use similar specs. They are smart.

Yup. People who think this isn't going to sell in this current era is delusional.
