The aggregate HN community seems to be reacting pretty negatively, but I see a lot of value in high-level &quot;magic&quot; tools (like this and Otto) that abstract away configuration for developers. While everyone else commenting is likely more experienced and thus feels more comfortable setting up the required config files, I am still a relatively novice web developer. Tools such as Nanobox and Otto provide a way for people like me to start using the right dev environment management processes without being overwhelmed.
