I've found my last 3 Thinkpads (T480, T490, T14) to all be excellent for Linux work. No real downsides, everything works as it should. If there was one thing that's let me down, it's that their webcams aren't great with occasional audio issues. My current driver though is a Flex 5i Chromebook, running ChromeOS and Linux via Crostini. Last time I had a Chromebook, I wiped it and ran straight Linux. But now Crostini is incredible, very easy to set up and seemless with ChromeOS. It runs my dev projects without problems, along with vscode and obsidian. Make sure that the device has at least 8gb of RAM though.
At Chromebook it's possible to change included Debian LXC container to other distro and version, like newest Ubuntu, and have Linux app icons at Chrome OS menus:
I don't know if this is just me, but the keys in any Lenovo are like too close to each other. There's no gap so I often end up mistyping sentences, but I just use a mechanical keyboard anyways.
