What was the reason for the upgrade and why pay hundreds for it? Why not the Note 4 if upgrading based on tech specs?
I've been exclusively Android since 2011 (Xperia PLAY) and there are daily frustrations that they still haven't fixed. Even the "best" keyboards like Swype and SwiftKey are freakin' terrible without enough customization despite all the praise they get. iOS's keyboard has gotten worse (no way to see case without moving your finger out of the way and memorizing what color means what on a keyboard that can change colors per app!), but at least I can use it without turning auto-correct off.
AirPlay with AppleTV was another huge incentive.
Yes, I was rooted and using Google Now and thoroughly versed in the Android ecosystem (Google services, ChromeCast, etc). I had the full experience.
Screen size and capacity removed two more reasons I stuck it out with Android (had a 128GB mSD in my 32GB Note 3).
I don't know why a single person expected the iPhone 6 or 6 Plus to have "at least 2GB" of RAM. FFS, only the highest end Android devices have that much and no one honestly expected it to MATCH the high-end Android phones (never have and never needed to). Sure enough, people start acting like 3GB is the norm for flagship Android phones and 2GB is the bare minimum, which simply isn't true. Did people forget that it was RIDICULOUS that the Note 3 had 3GB? Just because the Note exists, we can't compare it to the other Android flagships because it makes our comparison less extreme. That's some might convenient cherry-picking. Nobody flipped out when the S5 arrived with less RAM than the Note 3 because we UNDERSTOOD that we didn't need 3GB+ for a 1080p phone. The Note 4 and other QHD phones coming with 3GB+ changes nothing until Apple wants to try QHD with 1GB.

Apples to Oranges. Let's be honest with ourselves and stop trying to find something to get angry about.
