Cost of SharePoint

Spealking of the Real Story Group, parusing their blog, I came across this post from Alan Pelz-Sharpe, discussing some of the expenses associated with SharePoint implementations. Here's an excerpt that I found interesting: "The truth is that SharePoint is not a cheap option, no more so than any other document management or ECM system....What surprises both us and our customers is that SharePoint can sometimes present the most expensive shortlisted ECM option after a full cost analysis is undertaken."

This is not something I have heard many other places, but something I've always suspected. I think we need more cost analysis on SharePoint implementations in the transactional content management world.
