You know, if Microsoft and Apple were going to steal from Xerox ViewPoint, they should have taken more. I still find annoying things in Microsoft Word that were just easier in ViewPoint.

Take sentence selection.
.
Microsoft Word; 1 click = letter, 2 clicks = word, 3 clicks = paragraph
.
Xerox ViewPoint (Circa early 80s); 1 click = letter, 2 clicks = word, 3 clicks = sentence, 4 clicks = paragraph
.
When you are writing, moving just a sentence in Word is cumbersome and stupid.

Rant off....
Just FYI, there is a little icon that looks like a PC and says "PC Emulator", that is how I got a Xerox job. Steve hired me (thanks buddy) in order to test the ability to run PC programs in a little window on the machine with icons. Yes, they wanted to be able to run PC-DOS programs because some customers didn't know how to use "icons".
