Samsung’s physical keyboard case, which leaked out early late last week, was not a prank.

The South Korean company today made the accessory official alongside the Galaxy Note 5 and Galaxy S6 edge+, both of which are fully compatible with it.

Samsung’s keyboard case is a lot like the Typo keyboard for iPhone, except instead of sitting beneath your handset’s display, Samsung’s slab of keys sits right on top of it. But this space would normally be taken up by a virtual keyboard when you’re typing anyway, so it’s not long you’re losing anything.

Samsung’s keyboard also works with the company’s software, so that the user interface is adjusted wherever necessary while the keyboard is in use. On the home screen, for example, your app icons are automatically rearranged so that the keyboard doesn’t block any of them.

The other advantage to Samsung’s keyboard is that its keys make contact with the display beneath them in the same way your finger or a stylus would. That means a Bluetooth connection isn’t necessary, and neither is a battery that needs charging.

But there is one big problem with Samsung’s keyboard case, and that is that no one uses smartphones with physical keyboards anymore. Okay, there are a small number of people still holding onto an old BlackBerry, but everyone else has moved on and learned to type on a touchscreen.

With that in mind, it’s hard to imagine many people wanting to slap one of these onto the front of their gorgeous new Galaxy Note 5 or S6 edge+. Would you buy one?
