The original Samsung Epic 4G was somewhat of a disappointment for customers, while others delighted in the changes it had from the original Galaxy S. The glaring difference was the inclusion of a slide-out QWERTY keyboard, which is definitely a polarizing addition. The Epic 4G Touch is the follow up and the first U.S. release of the Galaxy S 2, and this time, it's not bringing a physical QWERTY keyboard with it.
