No idea what you're going on about dev kits, I just quoted you saying Aya Neo is a small form PC, implying that's somehow different to what the Deck is, to which I replied and said that's what the Deck is, a handheld PC as Valve keep stressing since day one, forever, and you wrongly replied no. I never said its particular SOC has been in a gazillion other systems in that exact configuration or whatever else you wanna muddy the waters with. Shit don't stop being PCs every time a new CPU, GPU, APU or whatever is introduced to the field by a brand. The Deck is a handheld PC. Deal with it.
The Deck is a
standardized, single-configuration handheld PC, with a dedicated software compatibility component, and games being tested and graded based on compatibility with that one standard configuration. Its hardware components cannot be changed besides storage, and it is a single, corporation-backed and branded device that, much like a console, has games being specifically adapted for it, with a dedicated store (well, store section) listing those games.
Valve only stresses that the Deck is a PC, because it is so unlike a PC by conventional user metrics. Its hardware design is that of a console, the same as a Switch, and it presents a simplified, gamepad-focused frontend experience like a console does, but it runs a PC OS underneath that frontend. Valve needs to reiterate the PC thing at every corner, because it's vitally important for their marketing that there is no disconnect between the Deck and PC in the consumer's eye, despite all evidence to the contrary. Face it - no matter how you look at the Deck, if you don't see that Linux OS underneath, all you'll see is a console.
Would you call a PS3 running Linux, a PC? Besides the power and not being a handheld, there isn't much difference between the Deck and that.
In my opinion, much like the Switch it defies standard classification. I prefer to consider it a handheld PC-console hybrid.
