I know some here do just that, but for me my 7250 works great as a phone also and I have a bluetooth headset which I prefer to the bulkier Blackberry as well as it frees both my hands. The second reason is one less device to carry and worry about charging and the like. My BB is multifunctioning and it suits me just fine, no need for anything else. It even lets me log in to my machine at work and from there I can take care of any problems that arise there.
