WHAT IS GOOD AND BAD ABOUT THE IPHONE AND WHAT ARE SUBSIDIES?

I’ve been seeking at opinions and any infortmation which I can about the iPhone and have found a lot of people who aren’t which vehement about it (and a little for a little current reasons). Any opinions on the initial indication to be released? And a little people have been observant which they won’t be shopping it since of subsidies but I’m not for certain what which means. Any assistance on explaining would be great, thanks!
