Hi, Just curious - does anyone know how many lines of source code there are in OS X and how this has grown over the last few releases? Wikipedia suggests that Tiger has 86 million lines of source code - is this correct? If so then why does OS X have so much source code compared to Windows Vista which Wikipedia says has something like 50 million lines? I sort of expected a "less is more" situation here with more elegant code and less backwards compatibility. Also, what language is most of OS X written in? Does this account for some of the difference in source code line count? I remember being stunned when Windows 2000 went from 20m lines to 40m for Windows XP! At the same time Solaris went from something like 10m to 12m between version 7 and 8 IIRC. Thanks, Craig.
