I am new to the site... My boss asked me to look into getting him a PDA or BLACKBERRY. He is going to use it mainly for outlook email & connecting to the web. He travels a lot and needs to connect to his email whenever he wants to and not have to worry about hot spots. He travels overseas as well. Is there an advantage of one over the other? What do you suggest he should go with? Do you have a models in mind? Any help would be greatly appreciated.
