I posted this link because I am trying to learn more about the OSS business plan/ economic model plus my recent interest in IT adoption in small and medium businesses (because of my previous SBC center's involvement).
Open Source Hippie often claimed that there is great migration support avaliable in the OSS community. But not in this bloke's situation .... he had a bit of experience in hand but found the various vendors' support for his migration waning. In the end, he ditched the OSS migration exercise and found much productivity improvement and cost saving switching to the Windows platform. I sure hope Microsoft Small Business Center content owners can use this as a case study.
Quoted from the article, "The total cost of ownership is actually lower in this case (refering to Windows server managerment) than with Linux because of the hidden costs of the support.""

Crest Electronics chose a Linux operating system, then seven months on, the company chose to abandon it for Windows. Adam Turner explains why. Check out "Linux misses Windows of opportunity" (The Age)
