Outside the carrier stores and Apple Stores, I have yet to see someone with either a 6 or 6 Plus.
I also haven't gotten that typical "Oh is that the iPhone 6 Plus?!" "Can I hold it?!" conversation most 6 Plus users have had these past few weeks.
The first week I had my iPhone 6+ I got ask about it. Everyone wanted to hold it. I now have the Apple leather case on it, so I guess people don't know what it is at first. It was kind of cool being one of the few to have one, but it can be scary letting people hold it.
Oh and I have yet to see anyone other than me with a 6+. I enjoy that, but I know that will change soon enough.
