I have bounced back and forth, having had the original Droid, original Droid Incredible, iPhone 4S, Note2, and now Note3. I am also a Mac user. I'm mostly platform agnostic. I want the tool that best meets my needs. I have gone back and forth and even made a spreadsheet listing the pros and cons of the going with a Note4 vs the iPhone+. The iPhone has caught up with a lot of the missing features that Android has offered, though it is still lacking in some ways, though going with the iPhone offers incredible synergy for Mac OS users.
There are huge features I will lose out on either way if I go iOS or stay Android. I wish it was not so difficult to get one device that meets my needs. I narrowed it down to two main features that I NEED, not just want, there is a long list of wants that I am not including: 1. tethering and 2. a good camera
the Note3 camera has been awful for me, without good lighting outdoors my pictures are worthless. i need a good camera and can not carry my dslr all the time. the iPhone will not allow me to use unlimited data for tethering unless i jailbreak it, which i'm not sure i'd want to do, even when it becomes available.
if the note4 camera is good in low light, I will be happy and stay android. if it is as bad as i read some complain the s5 is with low light....i will likely get iPhone6+
the decision for me -- what is more important, having access to internet on my notebook wherever I am (hugely important) or having a once in a lifetime opportunity to take a photo of a newborn and finding that the photo looks like it some historical footage from the moon landing in the 60's? this is why I might end up going with the better camera over tethering and go iOS...
