Today's Tech: Samsung confirms IFA launch for Galaxy Gear smartwatch and Android far more vulnerable to malware than Apple's iOS

Apple co-founder Steve Wozniak has levelled a broadside at Microsoft stating that they are overly dependent on markets that were built up a "long, long time ago." Wozniak spoke about a number of subjects but zoned in on Microsoft's recent releases and outgoing chief executive Steve Ballmer. "I think in some kind of real dollar terms, Microsoft has been falling for quite a long time. It's [sort of] been resting on markets built up a long, long time ago, and that's pretty dangerous," Wozniak said. Of the outgoing Mr Ballmer, Wozniak stated that he didn't think his time at Microsoft was "as important or significant as Bill Gates'". The comments came after the news that Ballmer is to step down in the next 12 months as the company moves onto its next stage.

Samsung will launch the Galaxy Gear smartwatch on 4 September in Berlin at its 'Unpacked' event, two days ahead of the official opening of the IFA conference, a senior Samsung exec has revealed. Lee-Young-hee, Samsung's executive vice president of mobile, also said that the first generation device will not use Samsung's flexible display technology. "We will be introducing a new wearable concept device called Galaxy Gear at our own event in Berlin on September 4," Lee said. "The Gear won't have a flexible display. The new device will enhance and enrich the current smart mobile experience in many ways. It will lead a new trend in smart mobile communications. We are confident that the Gear will add meaningful momentum to the mobile industry." From Lee's description, it seems that the device will work alongside a smartphone rather than as a stand alone product that can make calls.

With the unveiling of the newest versions of the iPhone just around the corner, Apple is reportedly preparing to launch its very own trade-in programme. According to 9to5Mac, customers will be able to take an old iPhone – the iPhone 4, for example – to an Apple Store in exchange for a gift card, which can then be used to buy a newer model at a discounted price. The report claims that Apple CEO Tim Cook is unhappy with the number of iPhone sales currently attributed to Apple Stores. Apparently, 80 per cent of iPhones are sold via third-party retailers. 9to5Mac reports that "sources" have said that the launch of such an initiative is scheduled for September, but nothing concrete has yet been confirmed. If the alleged move does indeed come into fruition, it is likely that it will coincide with the release of the hotly-anticipated iPhone 5S and low-cost iPhone 5C, which are expected to surface on 10 September. It is probable that Apple will refurbish the old handsets it collects from the trade-in scheme, before reselling them in emerging markets.

Android OS devices are by far at most risk of malware attack, with 79 per cent of threats to mobile operating systems last year taking place on the platform, a joint release from the US Department of Homeland Security and Department of Justice has revealed. Just 0.7 per cent and 0.3 per cent of threats were to iOS and Blackberry devices respectively in the same period, according to the US government data. Android "continues to be a primary target for malware attacks" due to its large market share and open source architecture the release said. The problem is exacerbated by the fact that 44 per cent of Android users have not updated their OS and are still running the 2.3.3 to 2.3.7 'Gingerbread' version released in 2011. Gingerbread has a number of security vulnerabilities that have been fixed in later versions.
