Since switching to the new 15" MBP 2.0 GHz I notice often connection loss of Bluetooth. I have a bluetooth keyboard and a mouse connected. It tells me after some time connection lost, then a few seconds later connection is enabled again, on both mouse and keyboard. I have a second MBP 15 2.2 GHz and it has the same problem. Mouse is a Razer Orochi and keyboard is the Apple Bluetooth keyboard (the first version, the white one). The batteries are full. What can I do? It is really annonying, especially on the keyboard. It can happen that a key remains stuck until reconnect happens. The distance is only 0,5m. Nothing behind. With the old non unibody MBP I have never had a problem with Bluetooth and the mouse + keyboard.
