Apple Server Subscriptions reports on a new Server upgrade subscription from Apple:

    Apple Computer is giving buyers of its Mac OS X Server the option of signing on for three years of unlimited access to software upgrades for the same price it charges for a single, onetime upgrade.

    The Apple Maintenance Program for Mac OS X Server, available starting Saturday, is in part an attempt to stave off the threat posed by Linux and to grab Microsoft customers disgruntled with recent software-licensing price increases.
