the samsung epic is an exclusive model for sprint with obvious upgrades that the other models don't have. To have that exclusivity for your carrier it is a lot of money I bet. I think the captivate is one nice looking galaxy line up device but I would bet a lot of money anyone would choose the epic over that device for obvious reasons. That is why the price is more, and that is why I will be switching to that device from the evo I currently have. Its an obvious upgrade for the fact that it has a keyboard and super amoled screen that consumes less battery life. Not only that, but I will actually be able to play GAMES on it rather then passable apps. The evo does have the ".3" screen size larger, kick stand, and high resolution camera, if those are features that would make you select that handset over an epic, you will be one happy evo customer. To me, the .3 is definitely not a difference because of the super amoled, the kickstand I never use, it doesn't sit right with my case, and its not ideal, and the higher resolution camera?, lets just say I would carry a nice camera if I was out for best quality pictures, to me It doesn't make a difference in photo quality. Both are basically producing very nice photos for a mobile phone. EPIC is definitely worth the $50 extra for this model on my carrier.
