That said, I know I would be able as well to do digital painting in Designer's pixel persona, but would be pointless, as the advantages of using a "PS like" tool like Photo, disappear in that pixel persona of Designer, so, for that I'd rather just use CSP, SAI or Krita (I can't stand Rebelle, Open Canvas and Paintstorm Studio inability to deal with bigger than 10x10k (or similar) pixel canvases...).

Which are AMAZING tools for painting. But some of us value very highly the versatility offered to an illustrator, painter and general graphic professional doing other tasks besides just painting (but these advantages are also in painting) , reason why still can see an edge on using Photo or Photoshop for Painting instead of Krita, Art Rage or Corel Painter, to name a few.
