It's actually packed with tons of features, but I have two 7s and see absolutely no reason to get a phone until the XI or Galaxy s9 (or sX) comes out.
Edge-to-Edge with Dolby-vision - that's cool, but I'd rather all of that on my tablet. Wireless charging. Again, cool, but battery life isn't my biggest gripe in life, so don't need it.
The big hardware jumps I appreciated in phones were 3G, 4G and the jump to 4 inch screens. Mostly its been software advances like Whatsapp, Spotify/iMusic, Uber that have been most impactful
