Jef Raskin's ideas realized through GMail

Today I read this description of the Canon Cat, which is a famous computer design by usability guru Jef Raskin:

"...the Canon Cat, a small desktop computer that featured a very unique text-based user interface that not only lacked modes such as spreadsheet and word processing but didn't even use files. As I recall from my testing of the Cat, it was as if everything was a single program and a single document. You got from place to place by pressing the "leap key" that invoked a quick search of the document."

Sounds a lot like GMail. Check out this piece on GMail as the Notepad of the Web.
