Windows 8 failed to boost PC sales and now vendors are scrambling to find the next big thing. Companies such as Google, Apple, Samsung, LG and Microsoft are all said to be interested in wearable technology, and according to The Guardian, Dell is “exploring ideas in that space” as well. Sam Burd, Dell’s global vice president of personal computing, noted that while there are “challenges in cost, and how to make it a really good experience,” he believes that wearable computing devices are very interesting and appealing to consumers. Burd explained that devices and form factors will “continue to change” over the next five years, adding that “we’re looking at a world of lots of connected devices.”
