I'm currently a Mac user, I'm developing my plan to move to Linux. I'd like to not have to run windows virtually to run 'some programs'. I have a license for Photo and Designer, I would love to be able to use a port of these great products to Linux. I don't mind paying for software or services that are of value. I'd even pay a premium to see affinity software on Linux, but obviously would prefer not too.
I think there are forces pushing people out of Mac and Windows so having the choice of using great paid for software on Linux might be a good move for any software firm.
For what it's worth I hope Affinity considers this avenue.
