The PC/Mac wars are on again. After the past holiday feel goodery of that "Let there be peace on earth," ad, Microsoft is brandishing a series of TV spots that throw OS X under the bus for not having features expected of a 'modern OS.' The features in the series of ads which aim to make Windows 10 cooler and more useful are multi-touch and the Cortana voice assistant. Microsoft has dropped the gauntlet and Apple will likely respond sooner than later, we'll have to see if any of the March 21 announcements will offer an answer to Microsoft's new taunts. It's on!
