>this holdover was carried into modern times since some customers still used the old equipment. Even ASCII mechanical teletype printers will map lower case to upper case. They just have to ignore a bit. Five level codes have no distinction between upper and lower case. I think the real reason is just the convention caused by the fact that the printers produced upper case. People get to the point where they see the complete words/abbreviations as thoughts. It's really just a complicated shape. Since everyone will have to learn the new shapes I predict there will actually be some complaining about the change. Oh, and upper case letters are larger and more distinct. Some people are now going to have to hunt up their reading glasses and/or change their font size. Considering how simple the concepts are, it might make sense to skip the intermediate representation and just define some Unicode pictographs...
