I don't understand these arguments about usability. In my office we have a mixed grouping of Commodore 128's, PC's, CP/M machines, and Macs, all of which seem to operate just fine for the various tasks which are set to them. Some of these machines might be considered very out of date, but no one has problems using Wordstar on the CP/M machines, and the 128's do just fine with FAX reception, and transmission. The PC's run WIndows, and the MAC's do the desktop publishing chores. I personally feel that obsolencense is in the eye of the beholder.
