PDA security is a problem since "confidential" data can be moved to it..... It's one of those "overlooked" things right now..... They can take things out of the network that you might not want them to or, worse yet, they can bring things in..... Difficult subject when you have users that think they know what they are doing..... I allow on a user by user basis... I haven't denied one yet..... That doesn't mean I won't deny one someday.....
