Quick question: out of 10 laptops, how many come with built-in optical disc drives? Chances are, less than half. And even for desktops, CD and DVD drives have become increasingly optional, relegating the job of playing media discs to dedicated players or even consoles. Seemingly riding on that trend, Microsoft is now rumored to offer a USB flash drive option for its upcoming Windows 10 OS. Although a small move, it is one of the signs that the software giant is willing to change some of its more established practices to remain relevant in the market.
