Concur. My 2020 ThinkPad Carbon X1 is so well designed and is of excellent build quality. In terms of laptops, I love it so much, even more than my 2011 MacBook Air. The keyboard is great, the screen is great, the Lenovo software is un-instrusive, the battery lasts quite a while, the charging port is durable, the body is durable, the dock drivers actually work, it feels nice to hold, … I could go on.
I’ve done quite a bit of developing and field-debugging with it. Haven’t had any complaints, beyond the unavoidable “My neck hurts.” and “Why is Windows choosing now to prompt me to use OneDrive, scan for viruses, update its search index, and install some mystery .NET runtime updates!? I only have 30% battery left!!”
