OK, so I got a brand new $2500 15' MBP and hooked it up to a bluetooth mighty mouse. Here's the problem: when Airport is transferring data, the BT mouse get erratic and jumpy, and the faster the transfer, the worse the problem (ie: almost imperceptible when downloading at max speed over DSL (~500KB/sec), close to unusable when Time Machine's backing up to the AE base station (~2MB/sec)). Few Questions: -Could this have something to do with the fact that I'm running the MBP in clamshell mode with an external screen and keyboard (wired)? -Where are the antennas located? -Is this a software or a hardware issue and is it worth talking to AppleCare about? PS: enabling Interfering Robustness alleviates the problem somewhat, but it cuts my wireless backup speeds down to a third, so I'd rather avoid using this as a permanent solution.
