MacBook has poor Bluetooth range My current workspace setup is a black MacBook that is plugged into a 21" monitor, with a Wireless Apple Keyboard and Magic Trackpad, both connected with Bluetooth. The issue is, I cannot take the two input components more than 12 to 18 inches away without either adding a delay or losing the signal entirely. 

Is this normal? Is there anything I can do about it?
No, this isn't normal.  Considering the age of the machine, I'd guess that it's a failing Bluetooth card.  It could also be some sort of interference.
