I've been a solid user of a MacBook Pro for the past 9 years. The main reason for this has been because of both the solid build quality and the UNIX based operating system that enabled me to utilise the majority of development tools whilst allowing me to use the Adobe suite.
Development tools, especially PHP and NodeJS typically ran poorly in Windows. Plagued by strange compatibility quirks a significant amount of development time was spent overcoming that. Not so on OSX on my trusty Macintosh.
