What have they specifically done that has made your creative work more difficult? I'm a creative using a MacBook Pro and it's just as good for me doing audio work as it was 5 years ago. They've also been doing a good job with Logic Pro, with some big updates of the last couple of years. Even if they removed the headphone input from their laptops (which I don't ever see happening) it's not going to effect creative professionals because they don't use it anyway.

Final Cut Pro X is now unusable due to them engineering the UX for beginners (it's basically an iMovie Pro) and similar moves to cater to the lowest common denominator. After installing Little Snitch, I noticed my mac was calling home to apple servers for basically any action which slows processing/rendering.
