As for docking stations - AFAIK today a docking station means a cube attached to any laptop with a USB-C cable. Lenovo probably expects you to use this: https://www.lenovo.com/us/en/p/accessories-and-software/dock...
I guess some models still have lower resolution screens, but I didn't look at then when I was evaluating the various options.
Well this really sounds nonsensical. I wouldn't believe if someone else told me but I feel like I can believe an HNer on such a subject. Thank you for letting us know. I would otherwise not imagine this can exist and wouldn't check when choosing a laptop. Now I wonder if my laptop supports higher resolutions on HDMI.
> Carrying a docking station around defeats the portability of the laptop IMO
You are not supposed to carry them, they are meant to be put on your table and stay there, already connected to external monitors, power supply and other devices, waiting for you to bring the laptop and connect it to just the dock.
Nevertheless small and lightweight "traveler docks" also exist.
Even a ThinkPad?
