Why would you post this? This is has no reason to be posted here.. If you dont like the feel of it return it or suck it up don't go complaining to message board..
I am not OP, but I see plenty of reasons.
1. To see if others have the same experience. On this forum, people share their opinions.
2. If others do have the same experience, what they do about it.
3. Hope of improving future products. If enough people feel the same way, perhaps Apple will consider making some changes. It's the internet, and what you post no matter where, is available to any researcher with a bit of clue.
Furthermore, OP may find the iPhone 5 somewhat uncomfortable to hold, but there are many other positive aspects about the phone that outweigh the original complaint and decide to keep it. So it's not a black and white issue as "if you don't like it, then return it."
Ask yourself, have you ever posted a complaint to this message board? If you don't remember, look at your posting history. Hint "wifi..."
