If we're nitpicking: only the Apple IIGS used Roman numerals in its name. The first gens were styled '][' (Apple ][, ][ Plus), later it was '//' (Apple //e, //c, //c Plus). The Apple IIGS was released in 1986, two years after the Macintosh was introduced, so that wasn't the model Drew Houston was referring to. (“We’re in the Apple 2 phase of Dropbox,” he said, referring to the time when Apple hadn’t yet made the Macintosh.") Also, he might have been referring to the OS, not the hardware. In which case it's ProDOS.
