I agree. It is a gross over-simplification to make this type of technical decisions solely based on ideology.
Organizations are going to either pay MS for a (debatable) better product, or to technicians to bridge the gap of other solutions. We have to see the whole cost of ownership and the gains and loses in productivity. The case can be made that governments and non-profits should use FOSS exclusively, but they also have to be accountable for the productivity of their employees given their specific work flow (something that business should be more aware). (potentially) wasting man hours forcing an organization to use a solution that might not fit its needs basely only on ideology is far worse than paying a commercial company for proprietary SW.
I like FOSS SW, and try and use it and support it when I can (which isn't as often and as I'd like). However, I'm tired of false equivalences that get made when two products are considered equivalent because they do the same thing w/o any regard to how well they do it. We as technical users tend to just install something and move on: we're not always around to see how our users have to deal with the technical decisions we made for them.
Don't get me wrong. MS often leaves a lot to be desired, and you have to sometimes wonder what they were thinking (and sometimes you have to take it with a grain of salt and give it a try, and you might be pleasantly surprised) and it can take them a long time to react and make things right. But they seem to be trying, and hitting the mark more often than not (specially with Office).
On a tangent. IMO, the ribbon on Office 2007 was awful, and it took a lot to get used to it, and it was understandable to refrain from upgrading to it (and it was a good opportunity for competitors to close the gap and gain market share). However, Office 2010 is far more polished and the ribbon finally made sense (mostly the drop downs with common action items). I still go back to the documentation to find old and trusted menu shortcuts in old versions of Office, but I can see how Office 2010 makes life easier for most users, and specially for newbies.
