When comparing the specs to the Note 4 and Note Edge, Apple seems to have went backwards with tech a couple of years. 1080p, same 8mp camera 1gb of ram, really? Not thanks.
Are you into spec's or performance? How would you feel if a phone with perceived lower specs outperforms another phone in it's class with supposedly better specs? It has happened plenty times before. Athlon vs P4, remember that one? P4 high GHZ rating but slower, Athlon lower GHZ rating but faster. Another example would be the bus differences between the new GTX980 and the 780's. These phones are designed differently they run completely different hardware and different OS's. All the apps on the idevice are written in C++ and Objective C. Runs extremely close to the metal without the use of JVM's. The benefits of JVM's are portability and compatibility across hardware and software. Apple does not need that since they are self contained.
Does not mean either is better or worse, that is subjective based on the consumers opinions. It is just a difference in approach. If you like the idea of having quad core, 10gig, with a 40megapixel camera in your pocket then go for it. But there are allot of people that care more about the performance of the phone, the stability, the apps, the quality of photos, the business integration and other things as well. When you put all the factors into place and understand the tradeoffs that is when you can truly make an informed decision about a device.
