I disagree a great camera is a must have. This is targeting the person who wants single purpose tech rather than a do everything smartphone. If you need a camera on a trip, chuck one in your bag.

And these days a great camera isn't desirable anyway, if you go to a party now everyone is taking photos with keychain cameras like the kodak charmera or instant cameras like the fujifilm instax. These have atrocious image quality, but people like that more than modern processed iphone photos.
