I have two ThinkPads with me right now and I love them both. I'm typing this on a Gen1 X1 Carbon and to my right is my E495. Both run Linux of course (Void and temporary Fedora/Windows dual boot).

After years of use the X1's keyboard has one missing and one broken key and the fan tends to start making a weird noise when I move it but that's why I have the second one to replace it at some point.

I honestly don't think I could use any other laptop because for me the keyboard, its layout, and touchpad button placement are essential. I got really addicted to using PgUp/PgDown above the Left/Right arrow keys for switching workspaces and browser tabs with one hand. I also like that the Up/Down arrows aren't half the height of the other keys, I hate when laptop manufacturers do that. They're still smaller but just the right size.

Really the keyboard and the physical mouse buttons above the touchpad are the main reason why I got a second ThinkPad and not something else.
