You had to buy the adapter separately. You know, exactly like the SteamDeck?
Or are you highlighting there wasn't an official adapter available at launch? You know, exactly like the SteamDeck?
As far as I know, it wasn't official, and it was a workaround people found later, well after the PSP launched.
On top of that, and actually the main reason for that, is that the PSP was never planned or intended to be played on a TV. If you give me an official source stating that Sony always planned that as a feature, then I'll admit I was wrong, but that was never a thing until the Vita, and even then it came later in it's life, and it was a separate(and expensive) acessory. So no, not a hybrid.
It took a few months, but the Deck HAS an official dock, that docks the hybrid console, and not only that, but the Deck was marketed as such, as a portable PC that you could take on the go, or just dock and work as a regular PC if you feedled with it a little. It was there day one.
Available now.

It is even listed in their own website as being able to play as PC and I quote "Because it is one".Not only that, it also says that you can play on a TV with the right accessories(i.e. a dock). What is something that can act as a PC, a home console, and a handheld console? A hybrid.
