So true. So, Yesterday I saw someone using their laptop, and there was like this Windows Lock screen. And I was like „WAIT why the fuck isnt a terminal there. And where is my waybar on the top? Are those really Windows floating there, what Kind of machorchist would spend a lifetime dragging around Windows in their Laptop monitor?”
I used Debian, there is a version for the Surface if you do some searching, after install you need to update the kernel for everything to work as it should. But it's not that complicated, I just followed the guide that accompanied the update.
As for the touch and pen. Both works fine for me. I did find a whiteboard software that recognized both sides as pen and eraser. Though I've been planning on trying to install one note and test that on the linux version. Just haven't gotten around to it.
From my experience with a modern Thinkpad (A485); nothing if not outright inferior. The trackpoints on them are pretty terrible compared to classic IBM-era thinkpads (10-20hz polling rate, abysmal velocity curve). The physical durability of the machine might be above-average for business laptops, but the chance of the hardware failing in some major way within warranty seems to be quite high (among other replacement parts, I had 4-5 mainboard replacements done under warranty). The cooling solution on the Thinkpad I used to use was also a fair bit inadequate, and would lead to severe thermal throttling of the mid-range APU. Honestly between the reliability and torturous process to even buy a new Thinkpad from Lenovo, I just wouldn't bother.
