You don't have to look much further than the millions of Galaxy Notes sold to realize that Samsung is serious about the stylus, but the company's now made that commitment clearer than ever by buying a piece of Wacom. It's not the biggest of investments for a company of Samsung's size, but the $58.9 million it's laid out will give it a five percent voting stake in the company, and a further in with what is one of the world's leading stylus makers. According to Wacom, its share of the global pen tablet market stands at a whopping 85 percent, and its sales of its components for use in smartphones and tablets have nearly doubled from 2011 to 2012.

As for where the new cash infusion will be put to use, Wacom says that by March of 2014 the entire net amount raised from the sale of shares will be invested in "product development and manufacturing and supply system enhancements for products to be supplied to Samsung Electronics," adding that it aims to "expand its relationship" with Samsung even further.
