Breja: Hardly. Any PC games you can reasonably play with a controller are console games as well. No one's going to buy this to discover Fallout, Disciples and Starcraft.
Zimerius: it is appealing ! though i don't see me using the trackpads for total war or other rts styled games , where i also wonder about how much tension this device will attract in the used muscle groups....
You can hook this to a monitor and play sit-down PC games on it with K+M as per the IGN preview, similar to Switch's docking. This duals as a mini-PC and a handheld. No reason why you can't discover those games with this device, with a bit of modding on for Brood War.
fronzelneekburm: Lol, kinda makes me glad I paid $75 for a Chinese handheld that lets me play any of the 10 billion ROMS floating around the internet*. Hell, it even has SCUMMVM and DOSBOX support. I was able to play the gog version of Blade Runner right out of the box, just by placing the folder on a MicroSD card. Apparently, if you have the right firmware, you can also play Half-Life on it..
*And most of those are probably better suited for a handheld than the crap I own on Steam
Not very accurate comparing apples with oranges.
SteamOS and Proton are being optimized to handle games and the Deck also has microSD card compartment to upgrade storage size. They're in different leagues in terms of specs, so the premium you're paying for lets you play modern PC games like the ones demo'd (e.g., Control, Death Stranding, etc.). That's why this device is compared to the Switch, Xbox One S, and PS4 to gauge performance and value. I'm confident with some modding that people will emulate the same ROM library as your Chinese handheld with better performance.
