I feel like this isn't really a question you're asking so much as an attempt to suggest that it isn't easy or possible. It totally is, and I know it is, because I maintain a parallel working environment on a Dell XPS 15 for a bunch of complicated reasons. All my data is there, too. I hate that environment, so I don't work there often, but I could if I had to (such as a couple years ago, when my battery failed in my previous Macbook and had to go in for repair -- it was trivial to do my job from the (previous) Dell for a few days). This is possible because I do the things I outlined above. I use exclusively x-platform tools, like Office, when I use something with an obscure file format. My notes and management tools are exclusively in Orgmode in emacs. Etc. Also: *your, not you're.
