Emilio Raggi lives in Buenos Aires, Argentina, and has been managing IT Projects for the past 12 years. He was very much a Windows fanboy, until one day he had to manage an Ubuntu desktop deployment project. He was highly qualified as Microsoft implementer, holding certificates as an MCP and MCSE, and was a consultant for an MS Partner. Still, Ubuntu had its charms and won him over. He is now an avid fan, user, and promoter, to the benefit of his family, friends, and colleagues. He is also an avid student of philosophy.
