I thought to myself... If Apple really had increased the amount of RAM, surely they would have mentioned it as an advantage in their keynote. Then I thought a bit more... But 2GB is still less than most current flagship Android phones, so boasting 2GB of RAM really wouldn't put them in a good light, despite it having more than last year's model. Finally, I thought to myself.... surely with 4K video, they will need a boost of RAM, right? Then I remembered that when I had the Galaxy S6, it had many problems with RAM management despite it having 3GB of RAM.
Then instead of analyzing everything, I remembered that I really had no problem with RAM on my current 6 Plus, so I don't see why it'll be a problem here as well. Having more RAM would be nice if only to have applications reload less often, but it's not something I'm willing to get worked up about.
