said by onebadmofo:I simply would like to share files. Allowing users to have FULL access to create and delete as needed.
I'd also like to be able to access those shares via web page so that users on Windows, Mac, and iOS have access to them without the need of a VPN connection.
Server will save you time implementing a web server, so if time is money then it is probably worth the $20 to buy Server.
As Thinkdiff said, in many ways OS X Server is just a GUI to configure the built-in servers. There are some additional features, I think, but primarily it allows you to easily configure and use features bundled with every Mac.
I don't have much time and happy to have paid $20 for Server, primarily used for VPN and caching software updates.
