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. Let us know which you prefer in the comments.

That arguably gives the best of both worlds: you get the convenience of a slate form-factor when you’re more interested in content consumption, and then a full keyboard when you’re looking to get some words down on (virtual) paper. It’s a similar concept as we saw Toshiba and Sony follow with their Windows 8 tablets, though those companies opted for a slider mechanism rather than a second display. Samsung also throws in its S Pen digital stylus, for notetaking and sketching.

The downside to Sony’s strategy is weight. The base section of the notebook is as slim as a regular Samsung ultrabook, but the lid is considerably thicker than the norm; it has to be, to fit back-to-back displays. Although it didn’t tip back under its own heft, or prove too much for the hinge mechanism to keep the screen stable, you did notice it when lifting the concept notebook up.

Samsung isn’t saying whether the Dual-Display Notebook will ever get a commercial release, though the company was running IFA attendees through questionnaires about form-factors and expectations around battery life. Our guess is that the collective response to that will decide whether the concept makes it out of the labs or gets relegated to the back-burner.

Heterogeneous System Architecture is a catch-all for scalar CPU processing and parallel GPU processing, along with high-bandwidth memory access for boosting app performance while minimizing power consumption. In short, it’s what AMD has been pushing for with its APUs (and, elsewhere – though not involved with HSA – NVIDIA has with its CUDA cores), with the HSA seeing smartphones, desktops, laptops, consumer entertainment, cloud computing, and enterprise hardware all taking advantage of such a system.

While there were six new public additions to the Foundation, Samsung Electronics’ presence came as a surprise. The HSA was initially formed by AMD, ARM, Imagination Technologies, MediaTek, and Texas Instruments, but today’s presentation saw Samsung added to the slides and referred to as a founding member.

Samsung is no stranger to heterogeneous computing tech. Back in October 2011, the company created the Hybrid Memory Cube Consortium (along with Micron) to push a new, ultra-dense memory system that – running at 15x the speed of DDR3 and requiring 70-percent less energy per bit – would be capable of keeping up with multicore technologies. The Cubes would be formed of a 3D stack of silicon layers, formed on the logic layer and then with memory layers densely stacked on top.

As for the concept, Rogers described a system which could not only learn from a user’s routine, but react to whether they were smiling or not, whereabouts at the display they were looking, and to more mundane cues such as voice and gesture. Such a system could offer up a search result and then, if the user was seen to be smiling at it, learn from that reaction to better shape future suggestions.

Exactly when we can expect such technology to show up on our desktop (or, indeed, in laptops, phones and tablets) isn’t clear. However, Samsung has already been experimenting with devices that react to the user in basic ways; the Galaxy S III, for instance, uses eye-recognition to keep the screen active even if it’s not being touched, while its camera app includes face- and smile-recognition.

What you’ll get here is a lovely little high-quality mobile speaker set up quite clearly to compete with similar-sized speakers – you know who that is. At the moment it’s not quite possible to tell which unit is “better” so to speak as we’ve not had a full test of this Jabra device. But given the quality of Jabra products we’ve worked with before, great things are bound to happen here.

This Jabra Solemate device is being shown off in collaboration with the platform known as ClubCreate, a User Generated Content group that makes music mixes across the world. With Jabra and the Solemate on their side, mobile music mixes are sure to be on the rise. And with the style and super odd look of the Solemate, we’re definitely going to be interested in sporting it in public.

Look at this little shoe device. It’s not mean to be worn on your foot, but the hook certainly is there. Stick to the surface and let the beats roll out! This device will be available extremely soon if not immediately (depending on when you’re reading this, of course) through a variety of major retailers and Jabra themselves for $199 MSRP. You’ll be able to pick up either white or black – your choice!

Vast. Bright. Incredible. It’s easy to be broken down to just a few stuttering words when you’re in front of the 84X900: 4K is one of those technologies that proves truly jaw-dropping when you first see it. 1080p suddenly looks clunky and jagged in comparison; you have to get right up close to the Bravia’s panel before you see the individual pixels.

It’s not just the individual detail, though; it’s the smoothness. Sony was showing a looping clip of a young girl surrounded by landscapes and floating water bubbles, and there was no smudging or blurring, just incredibly life-like movement.

It’s not a small TV, in terms of thickness, but we’ve a feeling most people won’t object to that if they can afford the 84X900. Exactly how much that will require is unclear; Sony says the new set will begin shipping from September, though hasn’t given a final sticker price yet.
