I went with my wife to Baltimore this week for a conference.
Among the vendor booths at the conference is a company that makes software targeted at the businesses attending. Knowing that I am a programmer, my wife's boss asked me if I would talk with one of them. I cautioned him that this was desktop software and I am a web programmer, so I would be of limited use. He understood, but was curious what I would think.
This sounded like fun, so I went there after we finished our lunch (at the Hard Rock of Baltimore which seemed to be populated mostly by those of us from "Flyover Country").
Upon talking to the people at the booth, it quickly became clear that my questions were too technical for them, but they did their best. This software is sufficiently old to be what I would call DOS-based (green text on a black screen). They didn't care for this term - preferring text-based. They are also coming out with a new version that their pamphlet calls "windows-based", but they preferred to call it the GUI version.
I was mostly asked to find out about the GUI version, so I directed most of my questions about that. The girl I talked to indicated that the GUI version wouldn't be full ready for a few months, but that the text-based version was very, very stable.
Now (and here comes the interesting part), she also told me that the text-based version is much faster. I said something about it being faster for the computer, but not the user. She said "Oh. If you know the keyboard commands, you can actually use the text-based version very quickly." I nodded and told her that I was sure she was right.
