A great product. Camera is amazing. I was using Samsung earlier and was apprehensive to try IOS. But now I enjoy it. Siri is very helpful, truly your EA who can handle so much of your work. I also like the 3D touch. If you press enough, you get a second menu. Performance is good. The size makes it as a good combination of tablet and phone.
For speakers, I feel Samsung had better quality. Here if I put the call on Speaker, the clarity is not as much as I got in Samsung but it is fine with the handsfree.
