University of Maryland’s Smith Business School is handing a free Blackberry to each student. The reason is that it wants to teach its business students at the Smith School learn to manage the 24/7 access to data and people they’ll be expected to deal with as executives. Although we’re all Blackberry fans, we’re not too sure about the message this sends out to the students. Having a Blackberry doesn’t mean you should be answering all emails as soon as they come in, even if it’s at midnight. Got to show some restraint some time, if it’s really important they will call.
