It's obvious that United knows how many users there are for the software UC. The software is there and running well, even if it never gets updated. The main cost to United is the VAN that they are using, in this case Compuserve (now owned by AOL.) While I don't know whether Compuserve charges by the packet or by connecion time, It surely costs them more than using the web.

The decision to discontinue must take into account whether they would lose any of the current users. They must realize that those of us that are using UC software are willing to forego 500 miles per booking!

Personally, although I would hate to lose the UC software facility, I would continue flying UA.
