Sounds like Sony later introduced a stand alone peripheral to allow the PSP to function in that way. If its an after thought and late add-on its not really a core function or selling point of the main system, nor how its understood to consumers. We can argue PSP can be a hybrid, but it wasn't ultimately in most use cases.

Lets take a look at how Sony themselves refer to the PSP.

"PlayStation Portable took console-quality gaming away from the TV screen and out into the world as a handheld device and combined full-scale gaming experiences with innovations in online technology and media playback that had come to the fore with PS2."

Lets look at how Nintendo labels the Switch Lite:

"Dedicated to handheld play. Nintendo Switch Lite is a compact, lightweight addition to the Nintendo Switch family, with integrated controls. As a dedicated handheld gaming device, Nintendo Switch Lite does not support output to a TV."

Lets look at how Nintendo label the Switch

"Nintendo Switch is a breakthrough home video game console. For the first time, players can enjoy a full home-console experience anytime, anywhere."

I used my PSP as a home console for quite a bit when I was using the PSP Go docked and using a Dualshock 3 controller.

.....But it was never actually intended or marketed to be one, so I would say that it isn't. It was simply a handheld device that had an option to connect to TV but wasn't part of Sony's focus.

Was the Switch the first to be a handheld gaming device that could hook up to the TV to be used like a home console? No. But they are the first to market it as handheld and home console, and focused their entire generation based off that feature.

So, Sony went to all the trouble investing money into a feature that allowed you to hook up your PSP to the TV (with a DS3 controller no less), but you feel it's invalid compared to the switch because you feel it wasn't marketed well enough or was successful enough. The marketing/success is irrelevant. Sony invested money into a feature to be used by people. We can't invalidate that just because we feel the marketing wasn't right or it's success doesn't warrant mentioning it. 

The later model can't connect to a TV the Switch lite. From a technical standpoint the Switch is a handheld first

Assuming this thread was made because nobody agreed with you in the article? Looks like nobody is agreeing with you here either 😉

Why do you put PSP in a different category though? Both could be connected to TV's via passthrough cables/boxes and with both you can connect and use controllers too. They both work in exactly the same way. 

Geez...
Hardstuck we know you created this thread as an extention of the debate in the PS2 selling over 160 million units article, but over there, the topic of discusion was if comparing Switch's and PS2's sales is valid or not since one is a home console and the other is a hybrid. Nobody, no one said that the Switch was exclusively a home console. I think you came up this old "Is the Switch a home console?" debate just to deviate from the fact that, yes, you like it or not, people do compare their sales even thought they are different types of consoles, and I have very strong guess on the reason why you and JackHandy don't want the Switch's sales being compared to PS2's

The big thing for me is PSP is 480 x 272 even when connected to a TV. There no scaler of any kind or resolution selection from the PSP it self. While the switch give you options when connected to TV. For me to consider something a hybrid it has to do a bit more than simple output to tv at the internal screen resolution.

He just want a bit of attention, So let him have his shining moment.

PS: I'm eating popcorn seeing all this and its true :P

The marketing IS relevant, though. Sony themselves didn't see the feature as something worth marketing, which is why (I'm guessing) most PSP owners didn't know about it.

It wasn't designed with TV support in mind (as is evidenced by the lack of TV output with the launch model) and it wasn't designed to be a home console on the go (as is evidenced by the lack of TV output with the launch model, no controllers included with the system, nowhere to plug in controllers for local multi-player, etc.). There is no reason to think of it as anything other than a handheld you could play on your TV.

The Switch functions fully as a (admittedly underpowered) home console, it just also gives the option to use it as a handheld. The system was designed to take advantage of this functionality. 

They are not the same.
