I like where you seem to be headed. 
What is cost impact when manufactured in volume?

You save cost of jog wheel. Add cost if sevond PCB and (???) may have higher assembly cost?

How about cost to test? Similar.???

Yeah, it would help to determine when to stop :)

Not entirely sure about this. One would probably develop a movement
pattern that allows one to see the relevant bits of the screen. But
with the vertical movement, we should be on the safe side in any

Naw, Samsung's is a largely mechanical wheel. The fewer moving parts,
the better.

By the way, I made a first rough estimate for a north-south-symmetric
(1) Anelok case:

PCB size:       30.3 x 64.5 mm
Usable circuit area (2):
                about 27.3 cm^2
Case size:      33.3 x 67.5 x 8.5 mm
Case volume:    19.1 cm^3

(1) I.e., whether used left- or right-handed, the display is always
    vertically centered. The LED may have to be off-center, though.
(2) For the "core" circuit, without battery and user input mechanism.

For comparison, Anelok v0:

Usable circuit area:
                about 27.0 cm^2
Case size:      84.4 x 29.4 x 10.5 mm
Case volume:    26.0 cm^3

Dimensions have a tendency of growing, but this doesn't look too bad.
There would be two PCBs: one with sensor and battery holder attached
to the top of the case, and one with the rest of the circuit in the
middle. They'd overlap slightly.
