As a developer I used to have a secondary boot for Ubuntu for stuff that's reliant on *NIX tooling, like Ruby (Ruby on Windows is possible, but it's not worth the hassle).

With Windows Subsystem for Linux 2 I'm able to develop the same without having to dual boot and feeling just as native as running Linux on the system, and I can use Windows software like, say, Photoshop. Visual Studio Code integrates automatically, it's like I've got a Linux 'Window' open.

And when I want to switch off I'm back in Windows for a full gaming environment etc.

I'm completely switched over to full-time Windows now. Maybe not a good thing, but it sure is convenient.
