I have one of the lcdfans modded Thinkpads. It's a "T70"—a T60 with an i7, 16GB of memory, the old style keyboard, a giant SSD, and, importantly, a high DPI display.

It's an awesome machine but it might as well be a desktop because it's so bulky and heavy that I never take it anywhere.

I travel with my M2 Mac but that Thinkpad sure is a sleeper.
