Same, I bought a t480 but I went with POP OS. I bought it to see if I could switch to linux.

On the plus side its a solid and stable dev machine, iterm seems slower than the linux terminal. Rubymine, pycharm etc are stable. Google cloud shell freezes in browser sometimes but firefox quantum and chromium work pretty well otherwise. It also works great with my uhd monitor even tho it doesn’t have a dedicated graphics card.

But, I encounter screen tearing a lot on web pages. The trackpad is horrible in comparison to a macbook pro. There is some pretty nice support for multiple workspaces but they dont have the amazingly useful trackpad gestures.

I honestly feel like if there was a thinkpad with a trackpad as good as a macbook pro 2012 then there would be no problem switching.
