Do most ppl really buy apple for a flex tho? they got their marketing and carefully planned branding down pat. But I think the major motivating factor for buying apple is how different they are. The interface, workflow, in house hardware, applications. Apple's stuff is all very unique to their brand.
You know that feeling when u use a device and it's interface is just perfect, it feels right in ur hand, everything flows well, it's got apps and hardware tailored just how u like em and even the culture and community of the brand seems right for u? Ppl are drawn to stuff like that. Even if the cost is higher. It's like PlayStation, Xbox and Nintendo rivalry. There's distinctions to each that the fanboys will rip eachother a new one over.
My media class in college used macs exclusively. They've got a bit of rep in the design/dev world. I considered buying one myself at some point but yeah, they're cost prohibitive for my broke ass.
