I find this hard to convince. I mean, don't get me wrong here, it's a powerful handheld PC, but i have some dumbest questions in the universe here.

Does Steam Deck have physical cartridge? Can i sell my physical Steam games at good price?

That can be fixed for less than $13 or €13:

An USB-C-HDMI cable + a wireless bluetooth controller ain't more expensive than a Switch Pro controller without a cable.

Or if you also want additional ethernet and USB ports for less than 20 bucks:

Less demanding games (f.e. many indie games and point&click adventures) can be played in (native or upscaled) 4K with these cables; the Switch dock still limits to 1080p output.

Ok, not an out-of-the-box solution, but a solution. The question remains: who is it appealing to? I get there are some. But everyone thinking Switch is selling so much more based on the Nintendo brand power which propelled the WiiU in the stratosphere is lying to themself. Maybe it is not what made the decision for me. But something is it, which leads to better perceived value for the customers. And I don't think the "hardcore" gamers find a solution here, because hardcore gamers never made up a base of 100M.

A solution for what problem exactly?

It doesn't make a difference for Steam Deck owners if the Steam Deck sells 1M, 10M or 100M units. The Steam Deck doesn't need special versions of games, it can use the normal PC versions. Thousands of games* are already compatible and the number of good games that run well on the hardware will always go up.

For WiiU and Vita owners the low hardware sales were a problem, since they needed WiiU- or Vita-versions of games.

_{*(tens of thousands if we include the PC gamaes positively tested by others than Valve + emulation)}

That's such a weird goalpost to shift, you do realise there are more games out there than just Nintendo first party, and plenty out there that are adored by many, as well as having won awards themselves?.

There are games on the Deck that are also on Switch, so what's your point about Software beyond that?. If you're going to pin-point focus on just 1st party than you're entering subjective territory, and this thread isn't about just 1st party.

OT:

I knew this thread wasn't going to go well, given OP's history, but at the same time I'm still surprised at how some folks are again and again, showing up and still being utterly clueless on PC gaming of today, and still think it's stuck in the 2000's, like can some of ya'll just not willingly act so stuck in the past?

But at least you have the option. Good thing the Steamdeck has a larger library than the Switch...

Some people get 6 hours with Portal 2... With some people managing to push towards 8 hours with some decent tweaking.

The Steamdeck has games that span 30 or more years... Obviously the games you want to run is up to personal choice.

PC is basically purely digital. Has been for decades. And you get to bring your games library to any and all PC devices you own.

No. And selling your Steam games (Aka account) is against the ToS.

I just stream it over my Wifi network with it's 3Gbps wifi speeds... Bugger the cables.
I can also throw it up on any compatible display that way too, don't need to move the dock around and recable everything.

It was a bigger problem with the WiiU as it ended up with a very insignificant games library in the end... Which also took years to build up... And which got ported to it's successor console and sold at full price again.

Steam library had thousands of games on it's first day of release and you didn't have to pay a cent extra if you already bought those games for a prior platform.

The SteamDeck is a good solution for some people, no question about that. But I don't argue that. I argue the point made in the video that the Switch sells more because of brand-power and legacy. I argue the notion, that Switch selling more than SteamDeck is somehow unfair or due to secondary concerns. No, for most people Switch is objectively the better system, it delivers them more value. As interests are different there are surely some for which this is the other way around, no question.

I also shared my personal reasoning. And for me personally I don't even need the HDMI-cable as I already have a PC playing the Steam-games. So it is down to the mobile qualities, which as I mentioned are lacking. If for other people it is different, good for them, get that SteamDeck. But if that still are not many people, don't assume that the other consumers just made decisions that are bad for them personally.

Because I want a bunch of shit hanging out of it on the go. Like an Apple product

Is your Switch dock shit hanging out of your Switch on the go?

I'm fully aware and don't take issue with anybody who prefers PC over Nintendo.  I was just stating my personal opinion.  Nothing more.  Am I not entitled to my preferences?

For me the Steam Deck doesn't (legally) play Nintendo games.  As for 3rd party, I'll stick with my ps5.  Not too mention the ps5 has a number of exclusives as well.
