Well, I'm a "professional", and I use Paint Shop Pro, and one of my colleagues is using GIMP. We're making a living in an IT company and I had to adapt a portal's theme for a corporation. I'm not an artist, but a programmer, so I can't draw but I can edit, and I'm more used to lower level terms and thinking of images as arrays of pixels I do stuff to, not "paintings" with "strokes". Software like Paint Shop Pro is easier to understand and do stuff for me, not to mention way cheaper for the company. Somebody here is retouching the company profile pictures with the GIMP just because she can, it's free, and she's already running Linux. We both get paid for this, so we are "professionals". So what?
