These days I find myself splitting time between OSX and Linux, but when I'm on a Mac I like my development environment ready to go without having to do much clicking around. While I have tried a few times to get away from using MAMP, I find that it is just more convenient than configuring everything manually. However, I prefer to use the command line and have it run in the background without having to see it there in my dock and making me feel guilty for not configuring everything myself.
