- The best way to provide a help facility is to make sure users don't
- need help very often, like on the Mac. The ballon help is really
- nice for novice users, and you can turn it off when you are familiar
- with the OS.

- Perhaps the .Xdefaults should be generalized for all UNIX commands??
- Something like: ls*F: G would replace the F option in ls with a
- G instead?

-
- This is feature, not a bug! Have you ever worked with a record
- oriented system like VMS? You spend most of you programming time
- defeating the file system :-(

-
- All shells are the same, since they all share the same weird
- restriction that the user know a specific language to converse with
- them. VMS is more wordy, but none the less has specific commands
- that you just have to know to survive. We should be more concerned
- with what the new interface which will replace shells will look like.

-
- No, UNIX is better for these reasons:
-
- pipes
- make
- light sub-processes
- the path
- transparent networking
- network file sharing
- no RMS
- choice of shells
- machine independant, choice of vendor freedom
- vendor price and speed wars
- better hardware
- graphics
- it does't have DEC-this DEC-that all over (gak!)
- simplicity
-

-
- UNIX is like English. If it sees a concept it likes, it takes it!
- :-) There isn't anything wrong with this. UNIX is set up
- flexibly so that you can add all sorts of new concepts easily as
- software technology advances...

- PICK is not dead, it's being used to run the Tax rolls in Moscow!
