Monday was all about the big technology companies planting their flags in the areas believed to have a mainstream impact in 2014 - but it was telling that their choices of which segment to claim leadership in was rather varied: Sony and Intel, which were both late to the smartphone party, were determined not to make the same mistake with wearable technology (Also excited about wearables: designer Michael Kors) Cisco and Samsung focused on the "internet of things," with the former predicting a staggering $19tn market opportunity over the next decade Google looked to the car, not so much as a driverless drone in the future, but as an entertainment hub that runs on its Android operating system AT&T also gave a hint of what future mobile pricing plans might look like, with the key word being "sponsored data." Much like toll-free calls, users can get free data usage -but only if they are connecting to sites sponsored by AT&T's partners. Some US lawmakers are already criticising the move as placing the US's biggest mobile operator in "the business of picking winners and losers on the internet." This excitement about the promise of new markets and new business models came, however, against the backdrop of more sobering news outside of Las Vegas. Samsung said it will miss analysts" estimates of fourth quarter operating profits by nearly a fifth, without really explaining why. Meanwhile China has only now formally (and still only partially) lifted the ban on foreign games consoles, highlighting the barriers that can still exist for non-Chinese tech and media companies to break into the market.

Its 13 manufacturing partners have each come up with their own design and specs. Bad blood - It's gone further than just the cut-throat price competition between market leader AT&T and T-Mobile. The smaller operator's flamboyant chief executive, John Legere, crashed AT&T's CES party while wearing his signature pink t-shirt. Mr Legere was escorted out by security.

Price and availability: From the $100s to $1000s depending on the piece, on sale now. by Hannah Kuchler Magellen RoadMate PND With Integrated Dashcam What is it: An in-car GPS navigation device that is also a dashcam Does it need to exist: The dedicated personal navigation device (PND) market is in decline - a victim of the success of smartphone navigation apps - so PND manufacturers are keen to add features that will help differentiate their products. But adding an integrated dashcam seems a little desperate and of questionable value. They said: "Our new RoadMate PND with dashcam not only gets drivers to their destination, it also provides recorded evidence of the drive."
