I am Apple fan, because of it’s reliability and software / hardware support. It’s been more than 4 months now, I am using this phone. And I have not faced any issue. If you use iphone you will never regret it. It’s worth the money you pay.
In terms of speed and quality of software, it’s way ahead from any other smart phones in Market. Camera quality is amazing. Spl for low light pictures. Image stabilization is upto the mark. As compared to Android phones, the specs are low, but if you test the software / gaming experience on iphone, it’s faster, smooth, and much better than other smart phones. I test my game play with Nexus 6 and the results were much better on iphone.
Overall It’s the best smart phone. Don’t compare specs with Android phones. IOS is way beyond that. Use it and then feel the difference.
Cons:
Data sharing with other phones is a huge task which I feel.
You don’t get so much of customization as other platforms have to offer.(But do you really need it:p)
