As someone who hopped over to the Linux side of the fence… same. Dual-booting somewhat eased the transition though, since I could do it more gradually and fall back to Windows whenever I needed it. Now that I primarily use Linux, I love how swapping to a new computer is 99% done by just copying homefolders. Even apps copy over, using user installed Flatpaks.
