I am going to practice a new technique that my girlfriend has taught
me:

- don't buy the thing for two weeks
- imaging how cool it would be, what utility and joy you might get
from it, how frequently/infrequently you will use it, etc.
- visit the website frequently. download pictures and documentation.
learn about it as if you owned it
- if after two weeks you still want it, then buy it.

Since learning this technique I have saved myself from buying all
manner of techno gadgets. In fact, I've bought little more than
groceries in the past six months.

PS -- full disclosu I already own a GPS and I'd say I get it out of
the flight bag for less than 1/4 of my fliying. When it is out, I
always do the same thing: set it down, on the back seat or give it to
pax for entertainment. After all, it's more fun to use my brain to
navigate. And yet... I do consider it an important piece of safety
equipment. It also is good at finding chinese restaurants in strange
cities for those important $100 egg rolls.
