In the meantime a beta tester reported that on his Tungsten T, the
brightness slider of the Tungsten T, put to the far left, doesn't turn
off the backlight as my one does. Furthermore, with the brightness
slider of my application, he was able to turn brightness much farther
down than possible with the actual brightness slider. Apparently the
lights in the Tungsten T series differ (quite much). One some devices
the actual range of brightness is smaller than the slider allows to set,
on other devices it is wider.

Now, I would like to add support for a calibration of the slider to my
program. Is there actually a problem with this approach, e.g. might Palm
had some reason to limit the brightness slider to avoid hardware
failures when setting the brightness to a very low level (which actually
in some cases makes the backlight flicker) or is it just limited because
Palm knows that some backlights have a smaller range of brightness than
others and took the middle value?

(I know, this isn't really a programming question, but rather a hardware
one)
