"No form-factor left untested" may well be Samsung's unofficial motto for Windows 8, with the company bringing a raft of prototype notebooks and tablets to IFA, Alongside the Dual-Display Notebook were four alternative concepts that played with sliding, swiveling, slate and other designs, as Samsung took a suck-it-and-see approach to Windows tableteering.
The Swivel model, shown above, follows the convertible notebook approach we've seen in Windows tablets before, with a touchscreen that can be rotated and then folded flat down onto the keyboard so as to make a ruggedized slate. That would deliver the same functionality as the Dual-Display concept, but with less weight thanks to only having a single screen.
The Binder concept is more unusual, with a touchscreen slate sliding into the docking slot of a removable keyboard. It's hard to tell how it differs from the docking systems of the Samsung ATIV line-up - all four of the concepts were behind glass - but it presumably has low-profile connections in the docking "gutter" so as to allow the slate to glide into place.
Samsung's Slider concept took a slightly different angle to the Sliding PC Series 7 the company showed off back at CES in January, with a form-factor more akin to Sony's VAIO Duo 11. The fixed viewing angle is a compromise, but the mechanism may well be more sturdy than a single swiveling hinge as on the first prototype.
Finally, there was the Samsung Memo PC, a smaller form-factor slate (somewhere between 7- and 8.9-inches, we'd say) with S Pen support, intended for those that don't need a physical keyboard. The asymmetric profile would be more suited to right-handed users, but it could be an interesting alternative to Samsung's Android-based Note series.
Of course, that's assuming any of the designs actually make it to production. Samsung is pushing ahead with more conventional docking-tablet designs right now, but was polling IFA attendees to see if they were swayed by any of the concepts it had on show.
