I'm upgrading for two reasons first, For the extra ram the iPhone 6 + is in need of more ram. I never had these performance problems with the 5s.
Secondly, me and my husband underestimated how many people were going to be waiting in line at launch day. (NYC) there were people there a week before launch day so by the time we actually got in the store there was only 16gb iPhone 6 and 6pluses. Since we had no other option we went for it. I can no longer deal with the lack of memory. My hubby and I will be more prepared this year.
Yeah, I can imagine a lot of people were forced to get the meager 16GB iPhone 6/6 plus when the 64GB models sold out quickly. If only Apple dropped 16GB and made 32GB the base capacity. My friend almost gave in to a 16GB iPhone 6 due to the lack of availability of the 64GB models. Thankfully, he resisted realizing that going from a 32GB iPhone 5 to a 16GB iPhone 6 wasn't a good idea, even with iCloud.
