Wow.
Firstly, both companies are trying to move away from each other. Samsung were the ones who cut the ties with Apple, not the other way round. Apple increased their orders with LG, exactly why we don't really know (Samsung claimed they weren't able to maintain the "huge discounts" they were giving Apple). Look at all the image retention issues that the LG panels are having in multiple machines (iMacs and rMBPs). Regardless, the displays are pretty much all as good as each other (this "yellowgate" thing is a load of rubbish, firstly for not being a gate, secondly for not being true), if you get a faulty one, get it sorted out. Nothing more you can do.
Secondly, nick.lidgett, what's wrong with wanting to stay on the same platform? What's wrong with familiarity, picking a solid product that you don't have to worry about, and not coping with the hassle of moving to new services and purchasing new apps all over again? And iOS is far from a fashion accessory: it may not bring as much as some of its competition, but it is still one of the most polished platforms out there (above Android in that respect). Doesn't make it the best, different strokes for different folks and all that. Clearly the iPhone is good enough for many people - look at the sales.
Finally...it has been discussed in another thread by others, but it's silly to deny that the iPhone completely changed the mobile industry, both redefining the devices as well as giving the competition a good kick up the arse to produce better products (which at least partially plays a part as to why Android is so good now).
