There is always the one App which isnt available elsewhere that prevents migration. I’ve been a full time Amiga user, BeOS user, OSX, user, currently I multiboot with Win11, Linux Mint and Haiku nightly, and Windows 11 still gets 99% screen time due to the one App. All other apps I use daily are cross platform.

For everyone its a different App. For me, Visual Studio 2022 and its world class visual debugger that inspects my complex vectors. Sadly, nothing similar (Xcode slow, QtCreator slow, etc).

I do enjoy Haiku the most, but cannot be as effecient when developing embedded libraries. I professionally develop cross platform libs, developed on Win11 but deployed on Linux embedded. Irony.
