I'm planning to buy a new laptop and I'm leaning towards a Linux PC, as I've been experimenting with working on Linux instead of MacOS for a few months already and I don't see any big advantage of MacOS that would be worth the price of a MacBook.
There's also a Windows PC but I don't even consider it as I love to work on a similar environment that all of my servers are (UNIX*) and I don't work with .NET stuff.
So, I'm very curious: why did you decide to choose your current workstation? Why is it a MacBook? Or why is it a Linux/Windows PC?
