> PostgreSQL is ACID compliant out of the box, whereas MySQL requires the use a of specific data store to get ACID compliance I'd rephrase that: MySQL is ACID compliant out of the box; it requires the use of a specific data store to avoid ACID compliance. InnoDB is the default, not MyISAM. Other than that I mostly agree.
