Today's Tech: Sony unleashes Xperia Z Ultra phablet and BlackBerry launches Secure Work Space to help cope with BYOD's rise

Sony has unveiled a trio of new gadgets. While the SmartWatch 2 is rightly causing a stir and the SPH52 Bluetooth handset looks like a neat add-on, the headlines are understandably being dominated by the launch of the Xperia Z Ultra, Sony's eagerly anticipated foray into the phablet space. Our first impressions can be best summed up as broadly positive, if mixed in places. Sony's Xperia Z Ultra has a number of feathers in its cap - most obviously, it's the world's slimmest Full HD smartphone. Sizing up at just 6.5mm in girth, the Ultra is indeed a slender beast. On the right of the frame are control buttons and a headphone jack, while the left-hand side of the device features a MagSafe-style notch for magnetic docking and charging via the DK30 accessory. However, super-svelte chassis or otherwise, there's no getting away from it - the Xperia Z Ultra is big, too big perhaps. For the rest of our hands-on preview, follow the link above.

Samsung has denied reports suggesting it is leaving the desktop PC market for good, despite leaks from the company stating otherwise. The Korea Times cited an unnamed source, who said, "Demand for conventional desktop PCs is going down. We will allocate our resources to popular connected and portable devices." The newspaper also spoke with another Samsung official, who said that tablets, all-in-one PCs and hybrid PCs are the company's current focus, and that it is restructuring its PC business towards them. Despite the doom and gloom, TheNextWeb reports that Samsung has issued a statement denying it is leaving the PC market: "The rumor that Samsung is withdrawing from the PC desktop business is groundless. Samsung will continue to offer diverse PC products according to consumer and market needs." It may be that the sources are entirely wrong, or equally it could be that the sources were referring only to a shift in resources away from desktop PCs to other areas, and not a market exit altogether.

An advisor to the European Court of Justice has said that Google does not have to delete information from its search index under European data protection laws. Niilo Jaaskinen, advocate general to the court, said that Google must abide by the law, but that it was not obligated to remove content created by others. "Search engine service providers are not responsible, on the basis of the Data Protection Directive, for personal data appearing on web pages they process," the court reportedly said in a statement, which outlined Jaaskinen's legal advice. The statement follows a complaint made by a Spanish man about the appearance of an auction notice of his repossessed home on Google's search engine. He wanted the information removed, claiming it was an invasion of his privacy. Since the view is not an official court ruling, the man in question may still continue with legal proceedings. The court, however, is likely to echo Jaaskinen's views.

BlackBerry has launched the Secure Work Space, an enterprise service that separates work and personal data on mobile devices. The new software is available for iOS and Android - a first expansion for BlackBerry beyond its own ailing devices. The primary features of Secure Work Space are containerisation, application-wrapping and secure connectivity, including secure browsing and attachment viewing. Applications can be managed, with the option to password-protect them. Most importantly, work data that is accessed or created in the Secure Work Space cannot be shared outside this, preventing accidental leaks of potentially sensitive information. Both versions come with access to corporate email, calendar, contacts, and notes and tasks, all through a single app. This is an area of growing importance, given the rise of BYOD in workplace environments. While productivity might increase with such an approach, security suffers, making it necessary to employ something like Secure Work Space.
