Yah, took a bit getting used to that back button but hey, at least we have one (Apple???). I see myself as kind of that Marcie type from Peanuts and I made my best friend start using Peppermint Patty. Seemed like a no brainer. I've just added a Moto 360 watch to the mix and am very pleased with it. That was more of a learning curve because it isn't very intuitive and the manual pretty much sucks but I'm getting used to it all now so I'm quite happy with it and my new G4. Glad I listed to my instincts.
