Apple have announced the long rumoured foldable iPhone, the iPhone Duo. It's expensive, and it's more than just a phone. I think I'm going to get one.

I'm not going to go into a big list of reasons why I want it, and the exact benefits it will give me. But I wanted to share my early impressions.

Admittedly, it's only just been announced, but it's already cleared up a few questions I had, and it's now got me thinking up more.

For starters, when I first saw the leaked images, the design didn't feel Apple to me. The hard vertical edge on the hinge, matched with the rounded corners on the other side didn't look right. The wider design also looked odd.

But after seeing the real design, and how the UI is arranged on the front and inner displays, made me forget those worries. Especially how it adapts to the new display ratio.

I also previously thought a foldable phone had two modes: open and closed. But the iPhone Duo looks like it can be more than that. You can use the front screen like a normal phone, you can open it up like a book, you can then rotate it to become a tablet, and it can even be folded into an A-shape and become a bedside alarm clock.

Something the Duo has which other iPhones don't is that it doesn't have the same silhouette as a traditional iPhone, so it doesn't carry the baggage of being familiar. To me, it feels more computer than phone.

Is it innovation? Other companies have released foldable phones already, and I'm an Apple fan, so I will always have a bias. But at least from the perspective of an iPhone user, it's innovation.

I remember when smartphones were getting bigger they were referred to as phablets. A sort of prematurely stretched smartphone that wasn't ready to be big. But then the iPhone 6 Plus arrived, and it felt more intentional. I think the Duo could be this type of product to existing foldable phones.
