Euromonitor International's industry analyst, Mykola Golovko, attended the International CES in Las Vegas, Nevada in early January. According to Golovko, ultrabooks were the biggest focus of the computer world at CES, with an impressive entry into the category by Lenovo. Its Yoga ultrabook blurred the lines between laptop and tablet. The other main attraction at CES was smart TVs, and again Lenovo led the way in innovation with a smart TV utilizing Android 4.0 – otherwise known as Ice Cream Sandwich – as its operating system. Golovko goes on to explain the other technological advancements showcased at CES.
