I just used my friends.
CANNOT replicate this issue.
Must have been a batch of small units. 600,000+ units on launch...think about it. Even with a 5% defective rate, which is plenty normal, is 30,000 units. They account for this type of thing, and Apple MAKES GOOD with defective units. Everyone calm down please.
Also keep this in mind: people are more likely to bitch than praise. There are likely thousands of people with good quality hardware in their hands, enjoying it rather than trolling the forums.
