Talent Economy reports on the surge of enterprise acceptance for GNU, Linux and other free-software and opensource solutions:

... the decision to implement open-source servers from Linux, Apache and Tomcat wasn't a rejection of closed-source solutions. Rather, the decision highlighted the need to choose the right products for the tasks at hand.

While many do report cultural effects in their shift to free software, for most the bottom line is still TCO, the bottom line of what gives the most bang for the buck with the least headaches, and those metrics are now tipping towards the community-produced and distributed costs accounting that is the hallmark of free software -- as the freesoftware "release early, release often" juggernaut bounds on, the costs of ICT freedom keep falling:

the Apache code registers a defect density of 0.53 per thousand lines of source code, compared to the commercial average defect density of 0.51 per thousand lines of source code. Another Reasoning study also conducted earlier this year finds that fewer defects affect the TCP/IP protocol stack implementation in version 2.4.19 of the Linux kernel than affect the protocol stacks of some commercial counterparts ... Open-source software is not merely straddling the fence. It’s scaled the fence, announced its presence and is now nose-to-nose with closed-source software.
