Or lack off in the 4s. What's happened to Apple? Loose home button, yellow screen, and now it rattles when it vibrates like something is loose. Build quality is good, but the quality control isn't! Meaning, when all goes well, it is well. Seems to be hit and miss with the 4s though. I'm not the only one, browsing forums, you get the impression this is the norm, and people are actually used to it? It's my first iPhone, and I haven't seen any electronic device with such inconsistencies in build quality. Apple products are expensive, you expect a premium product, in every aspect, but it's not delivering yet. Usually companies release a uniform product. I've never witnessed a Nokia phone that was different in feel and appearance to another Nokia phone of the same model for example. I know in their macbooks they use different types of RAM as well, Samsung being the good one, and the other brand, the not so good. It's completely random, they hope for an average satisfaction across their customers, which I have yet to see this philosophy being put to practice in other companies. This example isn't re. build quality, it's just their philosophy re manufacturing. Tells a lot in my opinion. I actually feel embarrassed going every other day to the Apple store, asking for a new device because the one I have is defective. Thank God for their premium customer service.
