I don't have the 6 but I have a 5S 16GB. I am going to be upgrade this year as 16GB is not enough. I also have an iPas Air 16GB that I am going to upgrade as well because of space. I don't know if I will be upgrading to the 6S and iPad Air 3 though. I am seriously thinking about switching to the new Surface Pro or another tablet and for the phone going with an android or windows phone. Every since Steve Jobs Apple has been slipping and are just not listening to their customers. Battery life on the iPhone is just not very good and I would rather they make a thicker phone with. Better battery life but they are just not listening. Plus the fact that there is no way to save everything to a hard drive or flash drive is a bummer. So unless there is a good reason to stay with Apple I think I will be switching. But I am going to wait until the new iPhone and iPad comes out before I decide what to do. Maybe Tim Cook will surprise us, lol.
