Apparently, a PDA comes into the same category as a phone and therefore has the same laws applied ie you can't use it while driving.
However, my PDA is a palm, where I store my diary and my contacts. It can't be used as a phone and I think it could be used to pick up emails but has never been.
I was running late for the dentist, and while sitting at a red light, I took my palm out of my handbag and looked up the dentist's telephone number. There was a police van behind me and they pulled me over.
What's the difference between looking a number up on an electronic device and in a paper diary or a business card stashed in a wallet?
I was let off with a warning but feel peeved about the whole thing. Made me even later for the dentist!
