Aesthetics and pricing.

Flagship android phones are usually more expensive than the iphones here in Japan since most of them don’t get the discount benefits that iphone gets. I would have no problem switching over to the new Galaxy or Pixel if it looks pretty to me.

Sync with my macbook is a plus, but it’s not necessary.

4 was most iconic.

But personally, I think 5s deserves the spot more with the finger print ring.
