Not sure if anyone at Serif will see this, but just to be clear at least for the people here right now: I downloaded Affinity Photo this week because of this thread and the promise of Linux support. I will be making the next event flier for one of the art collectives that I work for as a test.
If I can get it to work on Linux, I will buy a license.
If I can get it to work on Linux easily or there is a possibility of native support, I'll convert my entire consulting business and all of our artists to it immediately.
If there is native Linux support, I will tag it in every bit of media we post and I will include it in all of the presentations that I give here in Tokyo. (I do this with Houdini already)
None of us want another cheaper Photoshop alternative that runs on Windows. We want to be free. You're all so close to helping us get there.
Plus, hardly any of our digital artwork or experimental installations run on Windows, anyway. For artists creating at the edge of the tech that's currently available, there's a lot of code and customization and Windows just isn't an option. Mac technically could be, but what client would pay for the added expense of filling a room with that hardware? Even if the project has the extra budget, there's just no way they'd be so wasteful with it.
The future of artwork isn't happening on Mac or Windows. And as a company making tools for artists and shipping on these platforms, I think that Serif should be at least a bit worried about this. Whatever these concerns are about the Linux ecosystem or profitability there, I'd say they are outdated at best.
Anyway, no need to get distracted with any more of that. We can get back to technical details. = )
