I use Linux every day as a programmer and web designer. I have already bought all Affinity products, but unfortunately I have to boot the Windows partition in order to be able to use them. So far I have failed with wine, I could still install vmware or virtualbox, but that is somehow not very satisfactory. In short, I'm already a paying customer and I use Linux 99% of the time. I would be very happy if Affinity products would run on Linux.
+1 for a Linux version.
A great design suite like Affinity is exactly what is missing for a lot of frontend developers to fully switch to linux from mac.
