More importantly you have to trust it and all the software running on in, including the sony tools. Isn't that the bigger issue here?

I really find it difficult to believe that many fulltime Linux users would find it hard to get 15 mins use of a Windows box of some description for a suitably important task. It's more the principle that they don't want to and should not have to.

I have legitimate licenced Windows VMs running for various tasks where there is no alternative (except getting a different job). But if Sony and/or Jolla make a Windows based tool mandatory, then just on principle I think I will either stick to whatever community port is available, or stick my X on ebay
