I'm not even gonna read the rest of your post because that first sentence right here is already flawed and against your own argument.
why do you always bring up the Nomad. I am only talking about the Switch here. you said, because one can connect to a TV and the other can not, that this would mean we shouldn't see them as the same system. even making up this fictional scenario where the GameBoy was NES compatible to argue for this.
I say, the PSP also has versions that can be used on a TV and versions that can not be used on a TV.
therefore it is simply logical that you argument would also mean that the PSP 1000 and PSP 2000 should not be considered the same system in sales numbers.
so we would need to separate the PSP 1000 and E1000 models from the PSP 2000, 3000 and Go models due to the latter group having the TV feature and the former not.
if you argue that the Lite is not the same as the normal Switch then you also argue what I said above, as it is exactly the same differentiating feature between the 2 groups of PSP models
so to really ride this home... these 2 systems should not count towards the same sales pool if we argue TV out functionality changes what group a system should be in:
I bet there are some uninitiated forum useres here that couldn't even tell you which models these are just from looking at these images
