Pixelmator would slot nicely into the same consumer set of productivity apps that ship with all Macs (Pages, Numbers, Keynote). Photomator will get them back into the market they abandoned when Aperture was shuttered.
Speaking of Aperture… am I the only person who remembers that Apple owns Claris? Why didn't Apple just hand off Aperture to Claris and say "just keep this thing working on new MacOS releases"?
