In Greg's world, the only important buttons on the kindle are on/off, page forward and page backward. Ignoring, for the moment, the importance of being able to turn wireless off separately from power (after all, Amazon is ignoring that too by moving it to software only on v.2), let's contemplate a design which implies that moving forward and backward in a book are equally important.
Or, let's put it this way. Turning that way <--- in a book is as important as turning this way ---->.
Maybe Greg's native language is Hebrew?
Just saying. Now that I'm done laughing.
Wow. I understand a lot of people don't grok the keyboard (these are people who apparently don't write in their books, thus making them either civilized, or unlettered idiots, depending on whether you are an Old School Librarian, or a person who owns their own books and believes that an important part of literacy involves producing words, not just consuming them). But this is _exactly_ why IT led design of, well, anything is completely pointless. Okay, unless it's something primarily used by IT folk.
