I heard kit kat android is very fast and more stable than iOS 7. But the next samsung s5 will have 2K 5.25inch screen 4GB of ram...2.4hhz 16MP camera with 4K video recording and other amazing things. I believe that apple needs to innovate to be successful in 2014. This time around specs will matter more than software. No way on earth that 16GB standard is enough for next year because the size of the apps will be huge and the camera will take up way more space and the OS as well. It's not enough for 2 years. 64bit takes up more memory for everything.
