I have purchased 6s from **iStore** on the launch day and availed the 50 GB airtel 4G data.
No doubt I could purchase any other phone at **72k**, like Note 5 etc, buy decided to go with iphone 6s as my exp with iOS is superior than android. I like android since they give lot of options to tweak. I am android app developer- use few android phones for test but overall experience for iOS is better for daily use. I have used couple of *Samsung phones* but did not liked them(?). Currently I am suing moto g(2nd gen test), Nexus 7(test), ipad mini and iPhone 6s(sold xperia z2 sold)
Now my likings on iPhone 6s
3d touch is amazing(i changed the setting for minimum pressure)
Camera is cool/love it
Phone’s look is great(for me)
2GB ram(for this I picked 6s otherwise I could pick 6) really useful for browsing
battery life for me is great so far with 3g(I use LTE only when I extremely need it)- I use it almost 24-36 hours
telephony is great better than any android
screen is natural colored
touch ID is instant / not even .001 sec delay
Just waiting for some time to make app for iPhones in near future.
