Given that I’ve let everyone let off a little steam in my comments in regards to Manifold vs Open Source vs ArcGIS, what can we glean from what transpired?

Plain and simple, all software sucks (and I say this as a software developer). On top of that, life is too short to get worked up about software (because it sucks remember) even if you get paid to push it or develop it.

Its all irrelevant!
