Beginning my Drupal 7 development today with a git clone of drupal, and setting up my local development environment with MAMP and Drush, I am glad to be started with Drupal 7 and excited to have that 8.x branch enticing me on, too. I know git will help ease the pain of site and multi-site maintenance against the latest Drupal releases, and Drush (4.x) will help blast through build, deployment, and management chores.
