Hey all, I am considering purchasing the 7-inch model of the Galaxy Tab to use as my primary cell device. I would be getting the European model, so whether or not I could use it for calls is not an issue. However, I am a bit concerned that carrying around such a bulky device and a bluetooth headset to boot would be a bit much. So the question is: Should I use it for calls? Has anyone tried this before? Does anyone who uses one of these on a regular basis have anything to say about its bulk? Thanks!
