Say Halo to Toshiba's Cortana-ready 4K convertible

Shortcut at the ready

Toshiba unveiled new laptops and convertible notebooks in five product lines with an array of screen sizes to help students stay productive. What sets Toshiba's new notebooks apart is that they'll launch with a dedicated key to access Cortana, Microsoft's digital voice assistant that makes searching easier on Windows 10.

To complement the focus on Cortana, Toshiba will also equip these notebooks with TruTalk dual-array microphones, which will improve voice recognition and quality when using Cortana or chatting with Skype. These notebooks will ship with Windows 8.1 and will be upgradable to Windows 10 when Microsoft ships the operating system starting July 29. Windows 10 will be a free upgrade to Toshiba customers.

Radius' 4K screen will make you spin

Toshiba's new Satellite Radius brings a visual punch with its 4K display, the first on a convertible notebook. The Satellite Radius comes in several models, but the star of the line is the 15.6-inch Satellite Radius 15 4K Ultra HD Edition, which packs a high resolution 4K display, besting the 2K and QHD panels found on many high-end Ultrabooks today.

The 4K edition features a 282ppi display with 3,840 x 2,160 pixels. Toshiba has also enhanced audio quality with built-in Harman Kardon speakers, DTS tuning and Slipstream port technology to reduce distortion and deliver rich audio quality even at the highest volume. Toshiba did not disclose pricing or availability of the Ultra HD Edition Radius 15.

Other models in the series include a 14-inch Satellite Radius 14 ($584, £370, AU$757) and a standard 15.6-inch Satellite Radius 15 ($842, £533, AU$1,092). All models feature a two-axis hinge that allows the screen to be rotated 360 degrees to convert between notebook and tablet modes.

The Radius 14 has a brushed resin black matte cover and metal palm rest, and comes with either Intel processor or AMD APU. The Radius 15 features a brushed metal case and comes with Intel's fifth generation Core processor.

Both models come with two USB 3.0 ports, single USB 2.0, fast 802.11ac Wi-Fi and SD card slot. The Radius 14 and Radius 15 will be available at Best Buy on June 21.

With Windows 10, the Continuum feature will bring tablet optimizations to the user experience once the notebook is converted to a slate form factor.
