Listen, I think e13 is a great company. They make great cases (priced kinda high though) that fit excellent and they have great customer service. But if you honestly sit there and say that those two cases do not look exactly alike, then you need glasses. You have been on the e13 band wagon since day 1 but the e13 design is far from unique. The other case was out for months and months before the e13 ever came onto the scene. Every single part of the e13 case is exactly like the other one, just like the Atomic is exactly like the Element. Its very very obvious and its no big deal but people shouldn't come on here and say they can't see the similarities because its painfully obvious. On that note, I will not hesitate to order a e13 when the Verizon version comes out which is hopefully soon.
Having used the Fitted, I can tell you they are not as similar as you think. The fact that they both follow the lines of the phone and have cutouts for the controls guarantees that they'll look similar. But the Fitted, besides being a full-back plastic case, has a much more boxy design than the e13, which has beveled edges. The Fitted has almost completely squared edges and an unusually high "lip" around the screen, which gives it a weird feeling in the hand. It also has a single cutout on the bottom for the dock connector and speakers, while the e13 has separate cutouts (probably because those little in-between pieces would break pretty easily if made from plastic). The top edge designs are also different, with the Fitted being asymmetrical (bigger cutout for the sleep button than the mini jack), whereas the e13 has a symmetrical design, with the "high-spot" between the cutouts being centered on the design.
