Chinese eReader maker Onyx International presents a curious device at the Hong Kong Electronics Fair-- the Boox Typewriter, a laptop/tablet hybrid device featuring an eInk display.

Like other hybrid devices, the Boox Typewriter consists of a tablet-style display and a detachable keyboard. The display is a 9.7-inch 1200 x 825 Carta eInk number, and handles touch input via either fingers or electromagnetic (EMR) stylus. It also carries a 1GHz Cortex A9 CPU with 1GB RAM and 16GB storage, and runs on Android 4.0, making it rather dated in tech spec terms.

Assistive technology specialist Tobii Dynavox announces what it claims is a world first-- the Indi, an all-in-one speech tablet for non-verbal communicators aimed at the consumer market.

The Indi is a Windows 10-based device. It carries outward-facing speakers with "exceptional loud and clear" output, while control comes through either touchscreen, switch or head mouse. Included Snap software promises intuitive symbol-based communication, making it ideal for users with autism, cerebral palsy, Down syndrome and intellectual disabilities.

Also included are environmental controls (ECU), social media, email and music, as well as access to thousands of Windows applications.

Sony is famous for releasing unusual devices in its home Japan, and the DPT-RP1 is one such example-- a 13.3-inch tablet featuring an ePaper display one can write or draw on via included digital pen.

Technically a successor to a similar device, the DPT-S1, the DPT-RP1 offers a "non-slip" panel Sony says makes use of the aforementioned digital pen better. It also has a thinner and lighter design that is as thick as a stack of 30 sheets of paper, while the processor is also improved.

Razer announces a refresh of the Blade Pro gaming laptop-- now featuring THX Mobile certification for display and audio output quality.

According to the company, the Blade Pro display is calibrated and tested for resolution, colour accuracy and video playback, while the audio meets THX requirements for voltage output, frequency response, distortion, signal-to-noise ratio and crosstalk for clear sound through headphones.

Back in October 2016 Razer acquired THX, the audio company founded by George Lucas in 1983. Over the years THX expanded its remit to certification of audio and visuals, and prior to the acquisition was working on a certification program for HDR< AR and VR systems.

Apple announces an unnumbered tablet refresh-- the simply named iPad replaces the iPad Air 2 while promising "best in-class performance at its most affordable price ever."

The iPad features a 9.7-inch 2048 x 1536 resolution Retina display (one lacking full lamination or anti-reflective coating, curiously enough) and runs on a faster A9 processor. It also includes 32/128GB storage, 8MP rear-facing iSight camera, 1.2MP front-facing FaceTime camera, dual speakers, Lightning connector, 3.5mm headphone jack and Touch ID built into the Home button. Wireless connectivity comes via 802.11ac wifi and Bluetooth 4.2.

Being a basic iPad model it lacks iPad Pro features such as the Smart Connector, support for the Apple Pencil and Smart Keyboard and 4K video recording.

A blog post detailing the success of Chromebooks in Swedish schools holds a device reveal-- the HP Chromebook x360 11 G1 Education Edition.

The G1 is a 360-degree convertible predictably aimed at the education segment. It features USB-C charging, rear/world-facing camera and optional stylus input, although Google does not specify what stylus(es) the device is compatible with. The company fails to detail what is inside the notebook, instead simply describing it as "the world's thinnest rugged convertible notebook PC."

If one is to take HP's previous ProBook as a guide, the Education Edition probably carries an Intel Celeron or Pentium processor, 8GB RAM and 64GB of built-in storage.

Samsung launches a pair of tablet offerings at Mobile World Congress 2017-- the Galaxy Tab S3 and Galaxy Book, with the first designed for media consumption while the other is aimed at professionals.

Both tablets feature HDR video support, as well as Samsung Flow biometric authentication and improved S Pen support, together with 13MP rear-/5MP front-facing cameras, expandable storage via microSD card, fast-charging capability and support for Pogo keyboards with no separate charging or pairing required.

The 9.7-inch Tab S3 is an Android Nougat-powered number promising a "cinema-like experience" with a Super AMOLED 2048 x 1536 resolution display and a quad-stereo speaker setup tuned by Harman's AKG. It runs on a Qualcomm Snapdragon 820 processor and includes 4GB RAM, 32GB storage, integrated 4G connectivity and a 6000mAh battery. A next-generation S Pen stylus is included in the package.

Porsche Design unveils a premium 2-in-1 device at Mobile World Congress-- the Book One, a Windows 10 Pro hybrid with a more than slight resemblance to the Microsoft Surface Book.

As a Windows device the Book One has all the expected features, including touchscreen and stylus support via Windows Ink, the Corta voice-controlled assistant and Windows Hello facial recognition. It features a 13.3-inch 3200 x 1800 resolution display and carries an Intel Core i7 CPU, 16GB RAM and 512GB storage. Connectivity comes through x2 USB-C and x2 USB 3.0 ports, as well as wifi and Bluetooth.
