The talk is organized in terms of a neutrino mass models road map according to which the answers to experimental questions provide sign posts to guide us through the maze of theoretical models eventually towards a complete theory of flavour and unification.6 pages, talk at Neutrino '08, the XXIII International Conference on Neutrino Physics and Astrophysics, Christchurch, New ZealandHigh Energy Physics - Phenomenologytext
