"I really don't want to begin discussing regular Joe's desktop experience -- summarizing people into 2 camps trivializes the actual wants and needs of a computer user."You can put people into two camps about most anything -- enthusiasts, and everyone else.
This applies to cooking. Cars. Television. Sports. Video games. Interior design. Phones. Music. Architecture. Computers. Gardening. Reading... and I'm running out of objects by looking about my apartment, but the crux is that some people give objects and activities a large amount of attention when compared to the vast majority of the population - that doesn't give a rat's tail about anything beyond the most basic functionality.
Many developers, or at least the ones that frequent forums on computing topics, are just that - enthusiasts. They are very savvy, very passionate, and sometimes considerably out of touch with everyone who doesn't care nearly as much. There's a distinct difference between someone who waits months and months for a specific type of TV to come out, pays 4x as much for it compared to other TVs for its size, and can take advantage of all the features they paid for. This isn't surprising as they've become a bit of a domain expert on the points that relate to their needs. However most people just want the biggest, flattest TV they can buy for the lowest price.
Would I like random mass storage on the iPhone? Sure, why not. My mom? My mother after 17 years still doesn't know what directories her files end up in (Profile\My Documents or \Profile). She has my father assist her in getting her music on her iPod. Recently I said, "Mom, you use a computer every day. You need to remember where (Windows, OS X) puts your files" in which she retorted, "No, I just want to send Lorraine some photos. I don't care how it works."
And that's it. Most people want to just get something done on a computer. Most people just want to drive to the store. Most people just want to have fun with a video game and don't care how critically acclaimed it is. Most people just want a roof over their head that looks familiar when compared to other homes they've been in. Most people just want mustard to put on their hot dog and aren't espousing the qualities of some mustard on online forums. And so forth.
Everyone else is an anorak. And that's fine as there's a market that caters to them, whereas the rest of the population is still plumbing the first 10% of depth. Everyone is passionate about different things. And most people aren't passionate about most things.
