I'd love to buy a new Thinkpad But it doesn't exist.
Thick design: 15 inch 4k, backlit full keyboard, replacable big battery, replacable ECC ram, gpu or igpu but no Nvidia(swaywm on nixos), 2 ssds (zfs mirror), ports: rj45, usb-A and usb-c at all sides(left/back/right), hdmi
No need for webcam, fingerprintreader nor touchpad(trackpoint with 3 buttons is king)
And yes, it can be thick/heavy. If I need it light. I'll use a smartphone...
Privacy hardware buttons would be a bonus, as is open firmware.
