Without trying to be disrespectful to your wife's suffering, upon

reading your email I immediately thought of a double blind trial (

http://en.wikipedia.org/wiki/Double_blind#Double-blind_trials ) I

would run if it were me:
- Take your palm pilot and weigh it.

- Find some small object(s) of equal weight.

- Get two identical shoe boxes, some cushioning material, and wrapping paper.

- With your wife in another room, turn on the palm pilot and put it in

one box (and cushion it) and seal the box. Put the other object(s) in

the other box (with cushioning) and seal it.

- To make sure you too can't tell the boxes apart, leave the room and

have your wife enter it after you have left. Have your wife wrap the

sealed boxes in wrapping paper. Now neither she nor you know where

that Palm pilot is.

- Your wife should then pick one of the boxes and put in on her

bedside table or similar.

- After at most 24hrs (if she lasts that long) she should try the

other box. She should then tell you which she thinks has the Palm

Pilot in it.
Since there's a 50/50 chance, you could either repeat the experiment a

bunch of times and/or use a whole bunch of boxes.
Okay, totally off-topic (sorry), but that's what popped into my head.
