After beating my head on a wall with Adobe Illustrator CC for a month, I’ve given up and gone with GIMP and Inkscape.
Whilst GIMP has its own annoyances and quirks, I’m finding it much easier!
Granted, there was a bit of transfer-of-knowledge from AI to GIMP, which allowed me to comfortably use the latter in just a day’s time. But I was getting things done — happily, easily — getting things done, by the next day.
But Holy Ravioli folks, WHY is AI So Damn Freaking Annoying?
