Guys let's share our ideas here, the other thread is getting cluttered talking about three different mice.
At the moment we are leaning towards an IE 3.0 eque shape because it fills the next obvious void in the shape lineup (ergonomic without grip groove) and also because scream is a heavy advocate of the shape. Right now we would greatly appreciate input on siZe, materials, certain curvatures, etc... We think the IE 3.0 may be too large so we want to reduce the size and also most likely reduce the curvature. And obviously the weight needs to be kept down.
Keep in mind we are in the brainstorming phase so right now I'll just be absorbing any and all input I get.
