Can we get get representative data for a few interesting test cases?

I'm thinking of something like having several people read a large document in 
e-book mode.  If you record the timings on the keystrokes you can get an 
average time-per-page.  Even a stopwatch might be good enough.

Then just set up a system to loop through a large document at that rate until 
the battery runs down.

You could also make a few more runs with slightly slower or faster timings.

A few more runs:
  Wait forever (no keystrokes), just display the same page. (best case)
  No wait, just display pages as fast as possible.  (worst case)

Then there is with/without the backlight....

If the numbers turn out to be crap, then we will have a nice neat pile of 
crap numbers that we can use to convince other people that they are crap.

e-book reader is convenient because it is simple and easy for everybody to 
understand.  What other activities have some sort of average 
keystroke/whatever timing that would be reasonable to measure?

These are my opinions, not necessarily my employer's.  I hate spam.
