I am a Linux user since 2012, more or less, and I always use Ubuntu on my computers, and my last 2 laptops have been used Thinkpads, where I installed Ubuntu alongside(dual-boot) the already installed Windows 10.
I am not a fan at all of lock in, thus Mac are not even slightly considered as an option, not even to swap the OS with Linux as I see some doing nowadays.
I am thinking in buying one with 32GB or 64GB RAM, with SSD in the motherboard slot, and maybe 4k screen resolution.
Now, I am curious to know what laptops exist that developers are using with a Linux OS for development purposes.
NOTE: You can also suggest anything that runs with Windows 10, because Ubuntu will run on it without any issues.
