In terms of external displays i believe you wont have a problem with them considering on the x you could hook up a (standard usb 4) egpu and even on the non x with a dock you can get a 4k60 display (depending on the dock and maybe even freesync) I don’t think the cpu performance is the limit (it performs on par with a i9 4 generations behind but with 30W), nor the ram (windows paging is what makes win11 usable on that when gaming), although battery life on my z1e ally (non x) is awful but when plugged in that won’t matter. What I am concerned about is longevity of the hardware, its not like a standard laptop where the ram is socketed, the wifi card is socketrd (which I HATE, please do put that in mind this is a mediatek wifi card which isn’t replacable and has latencies that spike so bad for absolutely no reason and it makes remote desktop unbearable) although you can always plug in a usb to ethernet NIC on that hyptothetical dock youd be using it on

The amount of memory that is dedicated to the iGPU can be changed (at least on the normal ally non x) It’s a range from basically none (auto) to 8GB on my normal ally

Apart from screen mirroring and sms that everyone has mentioned the proprietary alternative undeniably has more features. I don’t know whether it is phone link or link to windows but one of them has a feature where your phone can be used as a webcam over WiFi. As someone who set up ip webcam on my phone and used obs virtual camera through most of the pandemic’s online classes it’s quite useful and I’d like to see features like that just work and are not relying on mjpeg and proprietary software on the phone end. Their auto hotspot feature i haven’t gotten to work and i think is useless but I’m thankful that i don’t have to turn off kde connect when using samsung dex.

apps like https://play.google.com/store/apps/details?id=com.parseus.codecinfo (https://apt.izzysoft.de/fdroid/index/apk/com.parseus.codecinfo) show whether or not you’ve got it, on my samsung galaxy note 20 ultra I’ve got software only :(

you can disable paging (swap) i guess apart from launching more things at the same time and letting apps know you have ram for them to cache shit (check app settings some apps do have a how much ram should we use slider like okular the kde pdf viewer) and virtualisation of multiple os’s i can’t think of much

I’ve been using a phone without a headphone jack for 3 years now with galaxy buds, if i didn’t accidentally break the included usbc headset id be using that instead (even on pc) but i did so now i use the headphone jack on my wireless xbox controller on pc (connected to my pc via usb because my motherboard’s audio makes noises when the pc is basically doing anything and echoes my mic into my left ear on windows (not a toggle in software or anything but said problem goes away if i power cycle pc by psu and then boot into linux)) and on phone i get to deal with Bluetooth and if i did have a usbc headset again i wouldn’t be able to use it and charge the phone in a practical way (wireless charging is an option but my phone discharges faster than it changes wired (when connected to pc), wireless charging is even slower)

nvidia, i swear most of the issues i experience are nvidia related in some way yeah i know using a GTX 1080 with a i7 12700k isn’t like the best idea but when given the options of use said gpu and get reasonable framerates with the games im playing (but get massive headaches when something related to the proprietary linux driver eventually breaks, and it does) or use the igpu and get unplayable framerates (or low res) or unnecessarily buy a newer gpu that isn’t that big of a jump in performance for me to justify the price I’m sticking with dealing with nvidia
