OK, I am not the "buy and return" kind of guy, so I made a lot of trips to the Apple store to play with the 6 and the 6 Plus. The 6 felt great and was a logical upgrade to the 5S. But I had never had a larger screen before. Coincidentally, I had several business trips recently, and I have been seated next to both 6 and 6 Plus users. Seeing them in the wild was pretty useful.
So after my last trip I went to the Apple Store and went with a SG ATT 128 6 Plus. Until now I had purchased white, but really liked the Plus in SG.
As everyone mentions, you do have to change how you use it a little, but that is coming very fast. Fits in the front pocket of all my pants just like my iPhone 5S did.
I have just two simple, immediate goals.
1. Learn to push the sleep button without dropping the ringer volume
2. Quit obsessing and trying to see if it is still straight
Challenging for us OCD types, but I do get over it. (with my 4 it was concern about battery life, with my 5S it was screen tint, but I do settle down)
So far so good. No kidding, the screen is beautiful.
