I used to use Pixelmator when I was on a mac. Its great for what it does, but its much much more limited than photoshop. Frankly most people don't need Photoshop. The UI is intuitive enough. I'm on linux now but missed that "preview" app for format/size conversions.

(It has a fun mosaic tool that lets you take a bit of an image and tile it real time which is really fun).

>Adobe must not be stoked about this news

Probably any mac developer should be a little worried. Apple has a mixed history at best with these applications. They had a lightroom competitor (Apeture?) they just dropped out of the blue. (some photographers are still griping) The "final cut pro" upgrade made people start using adobe again. But apple seem to keep the music making stuff going.

Frankly adobe Shold actually port their stuff to linux. The "free" competition is getting good (Krita, Blender, Gimp...). I have a couple pieces I used Gimp to layer together going into a gallery next week. Frankly its different, but pretty good once you get used to the UI.
