I’ve had had SP4 i5 8gb ram version since 2017. It’s unreliable when running Windows, let alone Linux. It had constant touch screen issues which never fully went away even after replacing the screen. When I tried installing Linux I decided to switch back to Windows after a couple of months as both wifi and bluetooth had constant issues. The battery life is 2 or 3 hours at best even if you replace the battery with a new one. I’ll be replacing it with an M2 Macbook as that’ll be way more productive than to keep using this Surface.
