Well it does help with travel.  I played Disgaea 5 in the morning while everyone was in chill mode on my beach trip on my Switch.  It also comes in handy if I want to play during my break at work or if I visit family overnight.  Not to mention the times I played for 2 and a half hours waiting for my night classes to start with BotW (obviously I am finished with Night Class now to be doing most of my gaming at home, but the point still stands).

With that in mind though...I just effectively remote played Horizon Zero Dawn on my break through my wifi hotspot on my phone with remote play on VITA, played all of the RE7 "Not a Hero" DLC at my parents during an overnight visit over their wifi with remote play, and the entire Alfheim section of God of War's main story over wifi with remote play.  So portability with my PS4 games is very feasible as well.

Granted it is much more convenient on Switch (by far), considering that most of my game time is at home before work or over the weekends at home, the VITA is also an effective option.  For those who spend more time away from home though, I would have a hard time not recommending the Switch.  I love mine to death, it is just has a disadvantage when it comes to the late release and price of 3rd party ports (which unfortunately is going to hurt western 3rd party support in the long run).

I know it is figure of speech... I was just joking because you lose money instead of winning it when you trade in, but I understand the concept of doing multiple trade in to make your 1 purchase of 60 into perhaps 4 games for 120.

So the millions of people that have bought a Switch so far, and the vast majority of whom play either in portable or mixed mode (according to Nintendo's own data) don't count at all. People like me that largely only have the option to play on portable systems like Switch, Vita, and 3DS should have nothing to cater to us? I believe Switch selling alongside PS4/XONE but not directly competing with them (much like previous portables have done) demonstrates that portability is very much a thing. While third-party mature games have not done well on the Switch, there are plenty of other games that have done well from indies to various Japanese releases.

It is also easy to infer that the games are inferior and such when you dismiss the central tenant of the system which is its portability, which is a key reason why people are buying the system. If this is the parameter that you are using to dismiss these ports from coming to Switch, I can just as easily and erroneously say console ports in general are not worth it because a lower-tier mid-range PC gets superior games that become cheaper a lot quicker than on consoles (which obviously is not true as there are people that like the convenience of console gaming).

I stocked up on way too many PS4 games using the ‘ps4 Games from 6-12 months ago are much cheaper than their switch versions ‘ argument...I even preemptively bought ys two days before it came out on switch as the PS4 version is 25 bucks In aus compared to 89 for the switch version...the problem is I now own about 10 PS4 games I have no time to play. It’s literally impossible I’ll ever have time to play em while I’m at home...the switch, for better or worse, seems to be the only machine I get to use. I have an overseas trip coming up in a few weeks and I’m even seriously contemplating repurchasing ys or wolfenstein 2 just for the trip.

Cool story bro. Not particularly interesting, mind, but whatever. So what is your point? Can't you simply have both systems? Why are we even comparing Switch and PS4 at this day and age? The two products couldn't be more dissimilar. If you want your Switch to offer you everything the PS4 has, then the chances are slim. 

The solution is simple: get whichever console or system your prefer, and buy the games that you want on it. Switch won't offer you portability with all games, as it won't get everything. Likewise PS4 will require that you are tethered to your TV at all times. Different products for different needs, with vastly different game libraries.

Furthermore, you expect too much from Devs. Sure, the Switch is easy to port too. But anything less than a few months and you end up with unoptimized crap - then people complain again.

Pick two. That's the triad of game development. 

Agreed on the portability, I simply don't like playing portable games, tiny screen, poor sound and usually terrible controls (Switch is no different in that regard). I had no illusion of getting great 3rd party ports when I bought mine last fall, that wasn't really the point of it for me, the point was getting those games that the other three platforms don't; namely Nintendo games. And every odd sleeper hit like Octopath.

Nintendo haven't done all that well with 3rd parties since the SNES, whether it be technical issues, developer/publisher relations or simply not connecting their user base with the titles on offer in any meaningful sense.

I generally agree and bought several times the Vita version or iPad version of a game instead of the PS3/PS4/PC version. Mostly visual novels (Steins;Gate, Danganronpa, Zero Escape series) and point&click adventures with minor graphic and input differences to the "big" versions, but also Dragon's Crown, Final Fantasy X/X-2, MGS 2+3 HD, Hyperdimension Neptunia, Atelier series and Shantae: Half-Genie Heroes.

On the other hand some people here have propagated the second screen advantages of the Wii U for years as central tenant of the system... and now the same people are begging for Wii U ports to the Switch where they don't have a second screen in these games.

I personally love the option to play games on the go. If the graphical difference and the price difference to the other versions are benign, I tend to buy the Switch version (f.e. indie games like Agatha Knife, Snake Pass, The Long Reach, Goetia and Thimbleweed Park). I was also going to buy the Switch versions of Owlboy, Nights in the Woods, Darkside Detective, A Hat in Time, but I already got the PC versions in Humble monthly bundles or from my secret Santa (sometimes even before the release of the Switch version).

I don't need AAA-ports with huge downgrades (for double/triple the price of the other versions) on the Switch since I have more than enough good games to play on the go already: AAA-games from Nintendo and AA-games from Nintendo and great indie games; also a huge backlog of Vita games and 3DS games. If these AAA-ports are in the bargain bin in a few years I may double-dip.

Nintendo said half of players were playing in portable mode. However, they don't specify whether they're playing inside or outside. The reason why people are getting Switch is the first party line-up. If portability were a major reason for purchase, we should see more 3rd party games with better numbers in sales charts.

Does it matter?

One, I have both.

Two, you missed the point of the topic entirely.
