software2,
I agree that in-house written software or spreadsheets have a whole level of confidence above that of purchased software....we are in agreement there. What I was comparing was the purchased software vs. "free downloads" or shareware.
The firms that develop, market and sell software most likely have a vested interest in doing a good job. After all, they've invested money and time into developing their software and user feedback does get around town. If they have lots of bugs, engineers will know it and this will hurt their company and investment. Free downloads, on the other hand, are from unknown sources who don't necessarily have a vested stake in the quality of their product.
Also, in-house written software can be just as full as bugs as purchased....its just depends on the talents of the writer.
