It certainly looks promising, but given their track record I will await the final release to see if Android finally will deliver an unified user experience. One of my issues with Android’s UI seems to have been left unchanged however: the schizophrenic back (soft)button that you’re never quite sure what to expect from… I hope they have something up their sleeve.
As a side note, after having watched part of Google’s keynote I will have to say that Apple does slightly better stand up than Google (but neither makes me laugh). Awkward scripts delivered by techies in an attempt to by funny rarely is.
