I wanted to make sure that everyone interested sees Adrian Brown's articles at http://www.thespacereview.com/article/1319/1 and http://www.thespacereview.com/article/1318/1 about the technical and budgetary problems with MSL that led to the launch slip. While I can't claim to be privy to the budgetary and political issues at the mission level, the technical discussion seems like a fair summary of the situation as I understand it, at least as good a one as can be gathered from public sources.
People in other forums have complained about errors in these articles, but without giving specific examples or providing any factual basis for their objections. I don't find that very useful. If there are real flaws in this account, I'd be quite interested to know what they are. p.s. I guess we need to change the name of this subforum.  -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.

I would say that Spirit and Oppy were a much bigger leap in technology from Sojourner, over a comparable time period, yet things seemed to work out just fine for them.
