I see they've removed whether each display DC or PWM dimmable from the psref... Or just forgot to continue adding that information. Get it together Lenovo!
No reason we can't have a second x4 M.2 in this laptop! Give us the ability to - we can always mod it a bit, but some of us need a laptop with 2 NVMes. And so far no usable Thinkpads have 2. Some have a massive numpad and offset keyboard. Some only have Intel CPUs and NVIDIA GPUs, which don't work well on Linux. Every single laptop has a major downside to the point that it seems purposeful. I'm not going to buy a modern Intel-based thinkpad because the last one I got couldn't even run the CPU at 10% without the fans spinning - and couldn't run the CPU at 100% for more than a few seconds without throttling.
Don't give us 5+ displays. Give us 1 good IPS and 1 good OLED (60hz doesn't count as a decent OLED). There's no excuse, go call up LG or Samsung, you can find a decent display to give us.
