--dead pixels
--dust under screen
--chips in the aluminum finish
--interlacing horizontal or vertical lines problem. Easily seen on blue toolbars, or when moving your eyes across screen, hard to explain but definitely present
--loose power/volume buttons
--rippling screen when pressing volume buttons
I had all of these issues over 5 different phones, all black.
I ended up keeping one with a chip in the aluminum finish and a loose power button as those were the least egregious problems.
Would have no problem buying another iphone 5 if Apple let me choose among 10 of them. Never had this many issues with any other phone trying to get a "good one".
Interestingly, battery life is worse than the iphone 4 it replaced, although the iphone 5 is light years faster.
I'm pretty sure that the iphone 5 will be my last iOS phone. Android will be ready for primetime by then. I can not justify the high cost anymore of owning an iphone. Quite surprised at how iOS has stagnated and how Android is only getting better. I thought that the maps debacle was completely overblown, until I went to a new city. Major, and we are talking nationally or world-renowned landmarks were in the wrong place. Just by about 3 blocks, but I would head South like the maps said, and I trusted my eyes that the big honking building that was in front of me, just like I had seen in the movies, was in fact north of me. My eyes were right. Mind you, I went straight off an address, which means that maps was getting actual addresses wrong. Maps wasn't wrong every time, but it was wrong alot of the time, so much so that I simply could not trust maps when I needed to get anywhere. How would I know when maps would be right and when it would be wrong? Completely lame.
All of the above issues would be more forgivable if the competition weren't alot lot cheaper. My unlocked device was nearly $900. Pretty ballsy, and if you're going to sell for that high margins, you'd better deliver.
