Linux

granted, but they are inextricably linked and you have to consider the software that does or doesn't allow you to utilise said hardware.

like, I've waited years for kernel devs to catch up to the proprietary hardware in my 2-in-1, namely the drivers for the ipu3 cameras. they are now obsolete and the focus is on ipu6 models. kinda important if you want this to be your main device.

and as to software, it's important to note that the touch-friendliness was an afterthought, so it isn't propagated through the system. like, in Gnome's own system settings app, you can't initiate dropdowns with touch! that's a pretty significant UI element that's been around since forever. another common stumbling block is initiating "right-clicks" on elements, by long-pressing stuff; sometimes it works, other times not. the on-screen keyboard usually appears when an input is focused, but it doesn't often enough that it's annoying.

speaking of, Gnome's OSK is only somewhat usable (and less so if you're on a non-US layout). if you're used to Android or iOS keyboards, it's pretty basic. however bad that is, Plasma's maalit keyboard makes Gnome's look like advanced alien tech, it's broken on so many levels you're better off disabling it. I didn't follow development in the past year or so, but one default "feature" of Gnome OSK was that it remembers everything you type - that includes passwords! - and helpfully offers them on the suggestion strip, with no way of turning it off!

obviously, the OSKs don't work if you need to unlock your disk on boot and I'm not sure they work on the login/lock screen; someone please correct me if I'm misremembering.

OK, screw OSKs, you're gonna use the cover keyboard. except, it's prone to just not work half the time. then you rip it apart (pardon, you disconnect it) and attach it again to have it working, maybe.

you're used to reading stuff, books, comics, whathaveyous, for hours. well, those screens aren't super power-efficient and the batteries aren't humongous either. plus, that thing is heavy and thick (easily twice my Samsung Tab) so maybe don't hold it up ABOVE YOUR FACE WHILE LYING DOWN - ask me how I know! speaking of screens, they aren't the greatest - try scroll-flinging a long page and watch this stuttering-flashing mess; you're gonna need new eyes if you keep this up.

I tried to make one work as a 3-in-1 solution. why have a desktop, a laptop, and tablet when I can have a single device and forego the constant copying and syncing and stuff. semi-decent specs, i5, 16 GB, 500 GB NVMe more than enough for my needs, so I got me a USB-C Dock, attached a huge 4K monitor, LAN, sound, mechanical keyboard, mouse... when I'm needed in the field, just detach it and off I go with all my shit on the drive AND I got a free iPad out of the deal, I just have to marvel at how smart I am!

yeah, nah. bottom line, they are bad as desktop replacement (throttled all over the place on account of anaemic cooling + whiny fan holler), bad as a laptop (on account of the kickstand, you hafta use it on a desk only, plus the keyboard is pretty bad and so is the tiny touchpad) and very bad as tablet (for reasons galore, some mentioned above).

so, like I said, as a fun project to play with - by all means, it's super fun trying out different OSs/apps (I haven't touched on Waydroid, Android x86, FydeOS, note-taking apps, etc.) but, as a daily driver, one that your livelihood and/or education depends on - hard pass.
