Are you over Blackberried?

I am somewhat guilty of being over reliant on a Blackberry. It sometimes is like that if you have been provided a BlackBerry by your employer - that makes you on-call 24x7. Sometimes finding a balance is hard to do. This article points out the fact that maybe we all shouldn't be overloaded with connectivity all the time. But realistically what employer would want people to not spend every waking moment working?
