That seems fair. Of course dependent on condition of both phones, and how much either party wants the trade to happen and the ease of facilitating that smooth trade.
I prefer the look and feel of the Samsung Ativ SE over the Icon, but the Icon has that awesome camera. It's nice to see two really nice Windows Phones on Verizon for a change.
I have the Icon and I'm very happy with it. It sits nicely in your hands. The button placement is well thought out. Very thin (but not too thin). No real appreciable bulge on the back of the phone. Gorgeous display.
