Ordered the iPhone 6 on launch day and love it; however, one of my friends got the 6 Plus and after playing around on hers I got curious, so I ordered the 6 Plus for myself. I've been using it for two weeks now and have yet to switch back to my 6. I am torn though, and time is running out to make a decision (glad for the holiday extended returns policy)!
One thing I have noticed is that I am more likely to pick-up my 6 Plus to check email, look something up on the web, etc. than either my iPhone 6 or my iPad Air 2. But, I can't really say that the screen, camera, and battery life advantages are enough to go through the hassle of having to sell my iPhone 6, etc. That said, I have grown accustomed to that big, beautiful screen...tough decision! Think I need to switch back to the 6 for a few days for comparison!
