I mean to each their own in terms of your use case may vary based on the UI/UX of your choice. I can see a need for OSX if a big chunk of your workload is going to be in graphic design, front-end development, or some kind of management role where you're spending days looking at spreadsheets or word docs.

I'm also not defending Linux as a consumer OS, but as an OS for use in a work environment tuned purposely to maximize the efficiency of an employee working as a developer who is deploying to Linux from OSX. I'm often bewildered as to why I run into so many back-end developers who are deploying to Linux, yet using OSX for their daily driver.

I suppose the hardware issues that you cite. I've had the occasional hardware issue, maybe once every two or three years that takes a couple hours to track down and fix. My workflow doesn't really make use of pointing devices, and I've never owned a bluetooth device that I've needed to connect to a workstation, so I haven't come across those issues. Battery would be a horrid pain though.
