After a week of non-stop Longhorn news, it's time for Apple Computer to let the big cat out of the bag. The next version of the Mac client and server operating system is set to ship today. We found this statement regarding Tiger Server rather provocative: "Since Apple doesn't charge for CALs (client access licenses), an Apple box running Tiger Server could do the same job as a Windows 2003 system for hundreds or thousands of dollars less." Could we see a Microsoft-funded study comparing Windows vs. Apple server total cost of ownership (TCO) in the not-too-distant future?
