For the record one of the points I was trying to (perhaps badly) make in the post (it's from my blog) is that I don't think it takes the economic considerations out of the equation. When I talk to developers their economic consideration is on the deployment side not on the development side. I don't think most people care that much about the cost of their developer tools as much as they care about the Windows 2008 license they'll need for every server
Fair points but if you (instead of your clients) are hosting code you will probably want to look to see if you're eligible for the BizSpark program which does include server licences.
