The SAURON survey of 72 local early type galaxies (ETGs) reveals an unexpected dichotomy of properties that depend on their specific angular momentum. Intrinsic shape, the nature of decoupled cores, age, M/L and ionised gas properties are all found to be significantly different for the ETGs with low specific angular momentum. I will present the SAURON results and report first results from the ATLAS-3D volume limited survey of 260 ETGs which give us a representative view of the local Universe and lead to a re-evaluation of the `handle' of Hubble's tuning fork diagram.
