Having a linux desktop and mac laptop, I prefer my linux box, and probably will not get a mac again in the future. I do Java and Ruby dev. Apple basically won't commit to java in the future. Apple updates do cost money ( not incremental updates) as well as most of their software. Now I'm not saying there are not free ones, but I want utility not eyecandy in most aspects ( and I understand people will probably not agree with that point) and the repository pretty much I can find what I want. In order to use a lot of the tools I want, I need to use macports or fink. Paths to hardware upgrades are going to be some what easier on hardware thats not mac, probably along with price of hardware. I use mainly cloud/web utilities for things like google apps, calendar, and email.. I don't care for a lot of the native mac apps, I really can't think of a single mac app that I use that isn't available on ubuntu.. but the good examples are things like iMovie and garage band. I really don't understand the point of development being more enjoyable, you're going to be living in a text editor and hopefully you understand commands to run things without a gui ( example would be code repository ). Also part idealism as well for me, I like be a supporter and advocate, and when if I have a chance to educate people and be interested in alternatives, I'm all for it.
As others have stated I think its what you do outside of development. Also you can look at the osx86 project if you're adventurous.
