For such a great UI, the lack of folders or at least tabs is astounding
I also have lots of apps, almost all the pages full. I travel a lot, so my iPhone 3G is stuffed with games to while away long airplane rides when I'm too tired to read a book. I have several navigation utilities that get me where I need to go, and lots of e-book readers, several news aggregators, and some technical utilities I find useful in my work. So yes, some of us do use the full complement of apps-space on our iPhones, and some of us really could honestly use a better organizing system, because the multi-page way of doing things, with no way of keeping things organized or categorized, is simply insane, coming from a company with such stellar UI props as Apple. And yes, I could probably use even more apps space as time goes on. And no, I don't use every app every day. Fortunately, I don't have ten-hour flights every day, but sometimes I'll have three or four in a week.
So my message to you cranky old coots who say "Oh, pshaw" between hawks at the spittoon to the notion of more than six apps on an iPhone: your usage isn't the same as mine, and mind the judgmentalism please.
