You are right, that developers are most of the time bad marketers. But I must disagree with the notion "... besides what he shows me had done" (I admit that might not have been your point, but I still want to loose a word or two about it).

That's a problem intrinsic with software: What you "see" is not what you get. You see a perfect polished UI, but you get a sack of bugs! So this criterion is not usable at all. The intrinsic values of a program are not visible to non-developers at all. Even software-companies have a hard time, deciding which criterion to choose as a base for decisions.

I think, when you look at cars or houses, people are more likely to ask a professional to decide about the condition of the car or house. Also everybody that loves his car (and life) will bring his car to some person that has read some books about motors and does repair the brakes "half-prize" in his back-yard. But in software practice, you just want to see some polished front lids of cars and decide that the brake repairs will be fine.
