I would disagree with your observation in that I never claimed that no needs can be fashion driven or that fashion is trivial, or that no one should be fashionable. Fashion and style are big business.
For analogy I have nothing against women who wear wedding dresses to a wedding instead of sweatpants and tee shirt, or people who market wedding dresses to women who want to wear them while getting married, it certainly fills a need for them very well, and profitably. The point I'm making is its pointless for a gang of construction workers to complain about women's wedding dresses, all "LOL they're selling wedding dresses how useless because the train will get stuck in the bulldozer hydraulics" and the other construction dude all "LOL yeah and how does she intend to get the cement stains out of that fabric anyway".
If your particular situation values style over usefulness more than any other device on the market, and some device fits your needs better than other devices on the market, hey, have fun with it.
Or maybe rephrased a basic product design goal is a fairly objective observation (although I may be wrong, but I don't think so). However, a (subjective) discussion about some users desires being trivial or non-trivial is way far away from that discussion.
I am making the claim that iDevices are not just a fashion accessory and in fact are a highly productive, useful mobile device for what people do with mobile devices. The success in the iPhone has been in large part due to its utility - the entire phone industry basically works like an iPhone does now.
Competing for customers remains a balancing act between increasing usability and the aesthetics/fashion of the device - clearly a gold iPhone has little to do with usability, but will sell heavily because it has a fashion edge in some quarters. But none of this would matter if the device wasn't still useful. My construction site superintendent step dad moves to an iPhone because it worked better than his BlackBerry. Rail yard workers I worked with are moving to rugged-case iPads over ruggedized PCs because the latter are difficult to use. Airline mechanics use them to log their daily activities and order parts. These folks don't necessarily move the needle of sales the way fashion does, but they wouldn't use an iPhone if it didn't help their job.
