It seems to be some sort of common complaint (especially from ua) but I often wonder how much of it is simply people finding something they can latch onto as a "missing necessity."
I do agree about the microSD card slot but there are a variety of reasons against it, from Apple's perspective. The obvious one is money made on selling extra space, but there's also issues with security, user interface, the real point of an SD card at all and why the average person would need it, and so on. Apple builds a closed playpen and they control all the entrances and exits. This is what allows iOS be so polished in the first place.
Moreso than the iPhone the real place I think an SD card slot is really lacking is on the iPad. But the same issues apply. SD cards allow the bypass of iTunes which allows a variety of problems to pop up in Apple's ecosystem.
