You're in such denial lol.
But hey, keep bragging about playing PSP games on a big TV. We're talking about 272p on big television screens of 720p, 1080p or 4K. And you want to use the zoom-in function of the TVs (which not all of them have btw) to further stretch that image? Lol. Oh and 720p on a small screen looks better than 4K on a big TV, just saying. ;) And whether you like it or not, the Switch is the first console where there's a performance difference depending on whether or not the console is docked.
Oh and the PS3 did exist, do you live in a world of alternative facts or something? Most of Sony's support went to the PS3, not the PSP. The Switch will get Nintendo's full support because it's a hybrid console, unlike the PSP, which was a handheld only console.
As for the Switch just being a more powerful version of the PSP, that's also total nonsense:
I presented you with facts. Just because the Switch adds a few bells and whistles does not make it unique. Listing things like HD rumble will not change the fact that it is still rumble.
Using your logic, the PS4 is unique too - it has the Dualshock 4. No other console has that so it is unique. It has a touchpad - unique.
The PS Vita is unique too - it has an OLED screen.
