I agree with your reasoning on items 1 and 2. It seems to me the essential trade-off is between items 3 and 4. Should the shift key be closer to the center of the calculator? Or should the [->] be closer to the center to help the folks doing degree/radian conversions (primarily)? My feeling is that the shift key is going to be used much more than the [->] key and therefore should be closer to the center. Therefore I think the shift key should be on the row with 4, 5, 6, and *. There is a secondary advantage for this configuration: Since there is no unshifted [Up] key, it will be more convenient going up in the menus if the shift key is next to the [Down] key. That way a person should be able to do "Up" faster. Having to jump over the [->] key to do shift and back to the [Down] key to get "Up" seems a bit inefficient. Regarding the pioneer aficionados, I do not think this calculator is really aimed at them. Right? -Jonathan |
