  Aye, this was my first concern. While I love the idea of a white
backlight, and would very much enjoy being able to read off my uMP2000 more
easily (I find the original Apple display a bit hard on my eyes), I am most
concerned with battery consumption of the backlight, which is already too
short for myself with the green display (my classes and note taking
sessions seem to last a long time, and it is not uncommon for my battery to
be at least 1/4 gone after a few hours if I need to use the backlight the
whole time and cannot connect to a power outlet). Sadly I must defer to
what the practical conditions of my situation dictate.

  Nevertheless I feel it is great what you have done, Mr. Grier. It is
indeed wonderful to see people still being both innovative and
helpful-contributory to the Newton platform! I, like so many, still lament
that Apple has not "come back into the fold." :-)
