The iPhone 6 Plus is a clearer iPad mini killer, at least until the only put dual app-mode into the iPad mini and iPad Air. I am a bit surprised that they released 16 GB iPhone 6 models considering that most new apps will now be coming with 2x and 3x icons, thereby bloating their size.
I'm also surprised that they're releasing a 16 GB model. Once again that "Apple tax" comes in to play as Apple's competitors offer twice as much memory for a lower price.
And I'm surprised that they stuck with a monaural speaker arrangement as well. A new model is a chance to improve upon shortcomings in the past.
On the Pros, I see larger screen and better camera, an equal to or slightly better battery life, and overall faster. But I wish there were more to talk about here.
