Pre-orders for the iPhone Duo begin this Friday, and the first units will be shipped to buyers on October 23. And there's a lot of hype around the Duo, since it's the first foldable iPhone ever — and represents the most radical change to the iPhone in a while. It's also the most expensive iPhone yet, starting at $1,999. Despite the price, the device comes with some trade-offs that we've already covered in detail. It lacks some popular features and the cameras aren't the best on an iPhone. Even so, many people are eager to buy one.
