Is Drupal 7 useful yet ?
My last review of the new Drupal 7 was rather cursory and I merely looked at the new release from the point of view and distrust of a salt-coated seadog perusing a modern ocean liner. So that review might have been quite biased as it puts habit in competition with progress. Quite naturally habit will win all of the time. To me Drupal 6 had become a habit, and habits do not die easily.
