Do you have a 6 or 6+? I sure hope not, because I can't see why you would buy one of those if you felt the phone that came before it was already low on RAM.
In regards to the comment you made earlier in the thread about the iPhone 5 being the iPhone to buy if you care about keeping browser tabs and apps in memory... maybe those are big things to you, but I have never, EVER met someone with an iPhone that has complained about those things. Only on MacRumors is this a huge issue. That's not to discredit those with issues or downplay the relative lack of RAM, but most people don't mind waiting the extra second for a page or app to reload. I agree that the 2GB will be nice for people like you and I that notice that kind of thing, but it's a non-issue for most people. I would never hesitate to recommend the 6 or 6+, although it's getting to the point where I would recommend that people wait until September.
