Why would apple want to make a browser if they can get people (from omniweb, chimera, etc.) to make some great ones for them. It just doesn't make sense. All of apple's iApps fill a void not filled properlly by other software developers. There aren't any alternatives (on the same scale and price range) to iMovie or iDVD. Whereas OS X has tons of browsers.
