Man, and I thought I was cool when I had a bleeding edge TI-89 with pretty print and the coolest calculator games (and the ability to do SO many more calculus and physics problems
)
Now they have PDAs and internet! Geez!
Anyways, on tests it always was and will be a good idea to restrict calculator usage. My AP calculus class had 2 part tests - one part with no calculators allowed and another with harder problems (numerically speaking) that calculators were allowed on. It worked out really well.
As for PDAs though, there's really little use for them in high school. They can write their homework down on paper like everyone else has. I'd just as soon prohibit them from school, just like laser pointers
