What is the page? The corporate R&D boutique or the retail shelve?
Ach!
The word is "shelf," not "shelve," regional dialects notwithstanding.
The "page" was the idea of a mouse, of a computer screen that was more than just a typewriter screen. It was such a revolutionary idea, but at the same time so obvious, it's hard to explain. All you had to do was see it and use it to know how natural it was compared to always typing in written commands. The "page" had Xerox's writing all over it before Jobs ever got involved.
