iPhone 5s is available at an Apple store near you.

Follow the review here:

What are its features?
  • It is the first smart phone with 64 bit architecture
  • It has an outstanding camera
  • It has finger print recognition system
  • The above in addition to other standard features.
Oh, Yes. It comes in 3 colors, Gold (very easy to seduce Indian and Chinese markets), Silver and grey. In fact, I heard that gold colored 5S is sold out in China. 



The A7 chip is at the heart of this phone with the M7 chip providing much needed motion related data processing.

Here are some of the details of the chips:

A7 chip was designed by Samsung using its 28 nm Hi K Metal Gate process. It is twice as fast as A6 and it is the first time 64-bit architecture used on a smart phone. Even for computers 64-bit is a recent introduction. 

The M7 Co-processor takes care of motion data from accelerometers, gyroscope, and compass.M7 lessens the load on the A7. M7 is from NXP Semiconductors (part number NXP LPC18A1) and is based on ARM's Cortex-M3 architecture. NXP details are found here:

About Touch ID

As a run of the mill user, I never bothered about this feature. I ahd it on my Toshoba Lap top years ago. However it is a definite improvement for the folks who use 123 as their password. Can it be hacked? Perhaps some one will, and they can claim the bounty offered by Nick(@nickdepetrillo) to anyone who can hack the finger print scanner.

The touch sensor and finger print detection depends on the A7 chip which was built with security in focus. This security feature if it works well in practice  (in business transactions)  may drive up the sales



Finger print detection is accessed via Home button(See picture).
