Since the debut of the iPod Touch, touch-screen surfaces have increasingly become integral features of many mainstream consumer technologies. The iPhone further fueled this obsession, and spurred a huge movement of "iPhone killers" which copied many of its features, but it was the touch-screen that captivated consumers. Samsung has done a fantastic job at capitalizing on this, their touch-screen cell phones being among the most popular non-Apples on the market.
