Lenovo ThinkPad X1 Carbon, the third generation model (fourth came out this month afaik). Advertising copy claims 10 hours battery life (driving like an old grandma, no radio, no AC, on flat terrain
) and fast charge to 80% in less than an hour.
High DPI ≈ 4K. Mine has an FHD, 1920x1080 screen, a very nice panel overall.
Linux hardware support varies across
component manufacturers,
caveat emptor, although I consider Intel to be a generally safe choice. Wi-Fi cards that need proprietary drivers and blobs are riskier. Switchable graphics can be quite tricky. Consumer HP printers with hplip drivers? *Shudder*
My exact model has been discontinued, it was from their build-to-order site and I ordered it with a French Canadian keyboard.
I like the keyboard on it very much, about as good as any scissor switch gets. In comparison, felt like it had slightly less key travel than the one on its T450s sibling. I've never really used the previous ThinkPad keyboard layout but have seen very polarized reactions from long time users. One thing missing IMO: Fn+ arrows for Page Up, Home, End and Page Down.
The top row keys (F-keys and a few more) should have had the same mechanism as the others, they don't feel as crisp. (Though certainly not hideous like the ones on the Sculpt Ergo.)
One "ThinkPad-ism" that might catch you off guard is the Fn key located
left of Control. I got used to it, those who don't can swap them in the BIOS. The keycaps don't have the same width, however.
The TrackPoint is a nice input device and save your hands multiple trips to the touchpad (or external mouse) and back. You can disable the touchpad in the BIOS.
