Well folks, I think this will be my last iPhone for 3 years. I usually grab the new one every year since the 3GS (I miss that phone). I was hoping it would have been the iPhone 6 Plus due to it's big screen (which I was waiting for), but the phone, for me, has been a nightmare and can't wait to be free of it. Now that the 6S Plus has 2GB of RAM, it should go the full distance. I'm going to get AppleCare+ for it which covers me for the 2 out of the 3 years I plan to own it. Sure future phones will have f/1.8-2.0 lenses. Sure it might gain bigger batteries. But as of now, I think phones have become good enough to go multi-year upgrades. Apple seems to support their phones for 3 years with OS upgrades. The 2GB RAM should keep things speedy. Wish me luck!
