Returned mine because of the screen and the keyboard issues.
The screen is way too reflective and glare-prone.
Was unusable on dark-themed websites and apps, and even in bright games my eyes were hurting from the glare after a couple of hours of play time. I have only ever used matte screens before, so I thought it was just an issue of getting used to it, but after using it for a few days it was still bothering the heck out of me, and I was struggling to see things on the screen where the glare happens, effectively covering what I'm trying to see.
I also appears that there is no protective layer of any sort on top of the screen panel, it looks and feels like an exposed panel, at least in the non-3D screen variant that I got, so you have to be very careful cleaning it as it's scratch-prone. Just cleaning some dust off with a micro-fiber cloth left scratches on it.
The keyboard is positioned way too far.
With fingers on WASD, your wrist is inside the laptop, which restricts the downward forearm movement and makes the laptop cut into your arm if you try to position the forearm even a little bit downward.
Also, if you wear a metal wrist watch, accessing the number key row will pull your hand into the laptop enough to result in the laptop and the wrist watch being scratched.
Lenovo really should have moved the entire keyboard one row down - would have resolved all these issues.
It's also a shame the numpad keys are short-width on a freaking 18" laptop.
The 1080p 440Hz display mode, but not utilizing 9955X3D is a bit weird, but I guess they were going for the higher RAM capacity and Thunderbolt 5, both of which only Intel offers.
