Horribly written.
1. Big screen is just a preference.
2. Faster processor isn't a must? Not having lag like the S4 is definitely enjoyable. And having a phone that will last two years without moaning and groaning when iOS 8 and 9 come out is definitely a must. Idiot.
3. It does have a bigger and better battery. Not surprised, wrong again. The processor was also designed to be as efficient as possible, using a 28nm design to save power, again see the anandtech review.
4. How many 128gb phones have been sold between all the manufacturers? My guess? Very little.
5. When upgrading a top of the line phone, you have less to improve upon. See also: S3 to S4.
