I can compare every Playstation console, be it fixed or handheld to the PC's game library and the PC will still have more games.

More =/= better. 

Every PC game is playable on the PC.

What's your point? 

The Physical version is not DRM free.

See the bottom of this post for 4 sources that disagree with you. You can attempt to change the meaning of DRM all you want, but that doesn't stop the fact that most AAA games on PC can't be sold or traded to others. Remember when everyone was up in arms because MS wanted to charge a fee to resell your game? Remember when everyone was up in arms because MS wanted to do 24 hour check ins for a game? Even in some alternate reality where not being able to play a PS4 disc on your PC counts as DRM, nobody would care. What people care about is whether or not a game forces you to prove that you legitimately own a game. What people care about is the ability to sell or trade games freely. The sales results of this generation are a testament to that fact. 

Older games should do 4k just fine.
The great thing about PC though is that when you buy/upgrade your PC... You can run all your older games at higher resolutions and settings.

Agreed. I pointed out logicalincrements.com's list of parts, as a source for my claim. You can see in their list, that they show that a 1K rig can play games like League, and less demanding games at 4K. Being able to play older games in 4K with a rig like that was never in doubt. 

I can stick my Steam games on an external HDD, plug it into a friends PC and start playing, no different from your physical games.

First you have to log into your steam account though, and that is when the DRM kicks in. It checks to see if your steam account has permission to play that game. And your steam game is still locked to your library. You can share it with your friends, but you can never sell it from your steam library without selling your entire steam account. 

And the reason why GOG games isn't DRM... Isn't because it won't run on a Playstation console... It's because Sony wouldn't allow it to run, that's the ultimate difference here.
The console itself is also DRM.

GoG isn't DRM, because... 

1. If I want I can sell my install file to somebody else. Sure, that would violate the TOS for GoG, but old N64 games used to come with similar TOS for physical versions, stating that you had no right to sell your physical copy. People ignored that, and anybody is capable of ignoring the GoG TOS. 

2. GoG gives you the option to download an install file that will never ask you to prove that you legally own said game. 

The Wii can't play all those Nintendo console released games over that entire time period.

It can play most of them, and that is enough to dismantle your argument. 

Your argument is ultimately irrelevant as I already stated that my tastes will differ from others.

When is the last time you sat down with a Sony or Nintendo exclusive and gave it a fair go?

That is a fundamental change in technology. It's a silly comparison.
The Playstation 4 is using x86, Graphics Core Next, *Nix derived OS, OpenGL and so on. - If it wasn't for DRM, it would be perfectly playable on a PC of similar build, natively.

Not all of my Steam games will run on my Linux computer. And it is identical to my Windows computer, except that it runs on Linux instead. Therefore DRM. Technological incompatibility =/= DRM. 

More =/= better.

Kudos to those who still find time for last gen gaming.  Personally for me, if I wanted to play my catalog of previous gen, I'd plug in my OG phatty and play away, but my backlog of current gen could last me through the middle of next gen at this point, and still more games will be released before next gen even starts.  How the crap people find time to game so much still blows my mind.. gamer since 89, but with work, family, and other things to take care of, I'm lucky to play more than a few hrs a week.  Crap took me almost 4 weeks just to finish God of War.

Anyways, OT.. do what you want to do.., personally for me, I'd rather browse and/or YouTube, exception being YouTube VR, off my phone, tablet, or laptop before I'd ever touch it on my ps4.  Same thing with other media.  Don't understand this whole multimedia narrative with consoles.  If I wasn't planning on gaming, then I'd do it elsewhere.  That's the point of a gaming console isn't it?  The games?

Edit: Sorry for the terrible formatting. Pema won't read my sources unless I put them here.

DRM stands for "Digital Rights Management." DRM refers to a collection of systems used to protect the copyrights of electronic media. These include digital music and movies, as well as other data that is stored and transferred digitally. For example, the Apple iTunes Music Store uses a DRM system to limit the number of computers that songs can be played on. Each audio file downloaded from the iTunes music store includes information about the owner of the file and how many times the file has been transferred. The protected files will not play on computers that have not been authorized to play the music.

Digital Rights Management is important to publishers of electronic media since it helps ensure they will receive the appropriate revenue for their products. By controlling the trading, protection, monitoring, and tracking of digital media, DRM helps publishers limit the illegal propagation of copyrighted works. This can be accomplished by using digital watermarks or proprietary file encryption on the media they distribute. Whatever method publishers choose to employ, DRM helps them make sure that their digital content is only used by those who have paid for it.

False. You can run every Windows game ever released on a Linux PC or a Mac PC.
There is one little piece of technology that can achieve this. Want me to point it out?

You simply cannot do the same with a Playstation or Xbox because the Operating System has several layers of mechanisms which prevent side loading/emulating/running of titles.
You actually need to HACK your console to circumvent it's security in order to allow the side loading of homebrew/pirated titles... That doesn't exist on open platforms like the PC.
