>It'd probably be useful to pick some other examples to discuss.

Maybe you can help with this, the author certainly didn't.

Let me try:

Firefox vs. Lynx

IDE vs. makefiles/make/compile

Word. vs Latex

Excel vs. ????

Outlook/Gmail vs. Pine?

Does one of those encourage expression over operation? Probably the closest is Latex, but still I don't see how it would be more expressive than what someone who spends equal time learning Word would accomplish with Word.
