OSS_ilation writes: In a conference call held this week to preview the upcoming LinuxWorld Conference and Expo in San Francisco IDC analyst Matthew Lawton cited an April 2007 IDC report that asked IT managers about top decision-making and purchasing criteria. The functionality, scalability and reliability of open source software topped the list. "The ones at the bottom of the list were protection from vendor lock-in, indemnification concerns, source code access and the ability to redistribute code," Lawton said. In short, end users today care less about whether they can tweak code and more about what the software does and how. The good thing for Linux is that a growing majority of end users still agree that the use of Linux results in considerably lower total cost of ownership (TCO) when compared with closed source proprietary alternatives.
