Should I get an iPhone 7?

I'm making enough money to pay for an iPhone 7 by monthly payments and I was just wondering if there are any cool features that make it worth buying and what they are.

Enough can

Sure

No. It is the worst time to buy an iPhone.

iPhone 8 is going to be launched next month and it is the tenth anniversary of Apple's most successful product line, so they are probably planning to make the iPhone 8 really impressive. All the leaks suggest that it is going to be considerably different from the current iPhones.

I suggest waiting for a month or two rather than get your latest and greatest iPhone become obsolete just after you buy it. Also, in case you do not care about the latest one, then still you will get a huge discount on older models when the iphone 8 comes out.

And don't buy any phone/personal-stuff on installments. It is a poor financial decision. Buy it only when you have enough money to pay for it in full. Take loans for things which will make you money, not for things which will just depreciate within few months.
