I held off on Windows 10 for as long as I could until my job required it. Now this nonsense. I hope this isn't the start of them joining on the web DRM bandwagon.
I tried Gimp for a longer time, too, but I could not get used to the complicated layer management, missing layer effects & layer adjustment features. I will try out Affinity.
Have you tried https://www.photopea.com/ ? It completely replaced my use of Photoshop and it felt very familiar where Gimp did not. Worth a look but ymmv
It took me a ridiculously long time to switch to GIMP and If I wasn't all in for FOSS I wouldn't have done it. I really can't imagine any of the designers I know using it full time.
Huge learning curve and a lot of missing features.
I have found most of the "high learning curve" is based more on work flow. Muscle memory can screw with you when trying to learn a new piece of software. I used to use Dreamweaver back in the day when I was on winblows, made the switch to Linux started using bluefish and had to change my work flow which was hard to learn because I was indoctrinated in the way dreamweaver worked. Actually had to relearn some aspects of web design since I had gotten used to the convenience of dreamweavers macros that were pre-installed
It's not an one-time purchase. I bought Affinity Photo for this purpose and then they released Affinity 2, and it wasn't a free upgrade for Affinity 1 owners.
I'm not buying Affinity 2 and buying every new release just like Parallels do. I'd rather stick with the old version or take a shot on Gimp instead.
Yes you can. Paying for a major upgraded version is the alternative to an evergreen subscription, but allows you to milk more usage out of your purchase if you don't need the latest and greatest.
Expecting a one time purchase to entitle you to updates forever is asinine.
