That's great for you, but I believe that the point of giving them to employees in general, especially those who have desk jobs and are not frequently on the road or out of the office, is to tie them to work 24 hours a day. They already had my personal cell phone number and that apparently wasn't good enough. There's nothing inherently wrong with the Blackberry (well, I could complain about a number of UI and other design decisions), but the implication when given one by your employer is that you should always be doing work.
