It is a real thing. I wish my photoshop skills were that good. I had to resort to 3d printer to make one. And here is version 0.2.
I found out that strap has to be as close to the narrowest part of a wrist as possible, thus needs asymmetric placement.

As for the form factor, I came to believe it is the only form factor which makes sense these days. I will explain. wp34s, awesome as it is, is just too big. This size niche is already occupied by a smart phone -- two devices of this size are too much and smartphone always wins. So, to survive as a carry item, calculator has to shift to a smaller cohort.

PS. About getting your own: I can post the shape file when I am done. I think Kinko's can 3d print these days. Or was it Office Depot?
