That's what we have field-upgradeable firmware for :-)

I'm thinking of giving it a length of about 45 mm. Depending on
how I hold it, I get different swipe lengths:
- thumb on the side: about 35 mm
- thumb from above: about 30 mm
- thumb flat, holding device diagonally: 40 mm and more, depending
on how much I involve the wrist.
The piece of plastic I'm holding there is the battery cover of the
Ben, about 6 x 4 cm.
Hmm, playing with it, I just realized that the by far most natural
movement would be to move the thumb vertically, like this:
By the way, Joerg has suggested the following design for a proper
Line widths about 0.2 mm, so the whole thing would be about 5.4 mm,
which looks like a nice size.

Heh, that could of course mean that it's patented. Wouldn't patenting
the wheel be just like them ? :-)
But yes, a wheel would work, too. E.g., the wheel of my dead Samsung
X830 feels right and it is about the same size as the Anelok design
One big benefit of a wheel pattern would be that I could conveniently
place the battery under it. Hmm ...

It certainly wins the style award :-) Generating that sort of pattern
looks tricky, though.
