I've been using two Thinkpad Extreme X1's for awhile now. I have a first-gen I use for personal programming projects and gaming and a second gen one that I use for work. In my opinion, they're wonderful. I dual boot both of them. The process was simply shrinking the Windows partition using the built in Windows utility and then installing Linux into the free space. I don't have any issues with the system sleeping or not waking up. I haven't really messed with hibernation though since I haven't been very mobile the past two years or so. The hybrid graphics work fine too, with one caveat. External displays require Nvidia mode, and mode switching can only be done with an X11 server restart. Hybrid mode has much better battery life but doesn't support external displays. My work laptop is generally plugged into 3 external displays so I keep it in Nvidia mode. I haven't tried Wayland, so I have no idea how well it works vs X11.
