Picked up mine from Sprint about an hour ago. So far, much, much nicer than my 3D! Paid full price for it, but don't regret it one bit! Its just amazing how light this phone is!
Will post a full review later tonight, but will compare it to my EVO 4G, EVO 3D, and my wife's Nexus S 4G! For those with a 3D, the signal on the Epic is like night and day compared to my 3D. Also, the speaker blows away the 3D!
For those looking for a horizontal leather pouch, the Verizon branded Droid X case fits perfect! This case hasn't let me down since the EVO 4G! I have a hard case on my Epic, and it fits in the case perfect. Highly recommended, though it is a bit pricey...
