I know I'm probably in the minority here, but I used a Galaxy Note of a friend while overseas and am definitely not a fan of the bigger screen. If the new iPhone 6 goes big, I might have to go to a windows phone. If I want something bigger I use my iPad or Laptop, no need for something that wont fit in my pocket!
But I do have my hopes up for some crazy battery life extension in this new version.... *sigh*
