Apple's UIs stopped being consistent ages ago. First there was aqua, then brushed metal, then garageband (wtf happened there?!?!? Wood effect?!?!?? You're bonkers!), then the pro apps UI and now we've got the iApps with the clipped window corners, gradient backgrounds and floating inspector windows. Apple's app developers must never have got invites to the 'Let's all agree on one UI style' meeting.🙄 Meanwhile the appkit/IB guys are sitting in their cubes going 'La la la, not listening' when someone tells them 'Hey, maybe we should support some of this new stuff in the dev tools?'
Edit: I'm not criticising the UI skins (well except Garageband's) but some consistency would be nice and I (and every other mac cocoa developer) would like to not have to reinvent the bloody wheel everytime we want to write an app.
