If you’re Mozilla or Apache ok you want Distributed VCS. Else you don’t need it. Really!
Unless Linus can convice you you need GIT. But if you’re like me, after the presentation (if you succeed into not falling asleep because of his so bad jokes) it’s more likely you will start hating DSCM tools which also not the best thing to do. You can just hate GIT and shout that Linus is B O R I N G and last time he checked what humor’s definition is was never.
