Is this in fact how it was designed, or just how it is photographed? And if by design, why? It seems like a straight edge would be lest costly than a bowed edge.

Perhaps not. If the overall cost consists of three main parts:
1 - preparing a mould
2 - plastic
3 - pressing
then 1 would be a little bit bigger with bowed edge, 3 would be the same but 2 (cost of plastic) would be lesser.
So perhaps the bowed edges enabled them to make cheaper body.
