Recognizing that iWork '09 and iLife '09 require Mac OS X version 10.5 Leopard, but not all Mac owners have upgraded to the new operating system yet, Apple Vice-President of Worldwide Marketing Phil Schiller on Tuesday introduced Mac Box Set, which includes the latest versions of the iWork '09 and iLife '09 software suites, along with the Leopard upgrade. The collection sells for US$169, or $229 for a five-license family pack.
