Palm Treo 600 (GSM)
Extreme Radio interference
I was watching some dvd's and the Rotel amps picked it up. Not the kind of thing I expect from a $5995 amp, but I noted that the Treo causes my monitors to wobble the image if it is sitting in the cradle or in close proximity to the computer.
In the car I get noise as well. Leave a home radio on and have your Treo in say ~10 feet of it, and you'll hear a specific pattern of noise, but it is not constant, it must be a network thing or something, but it SUCKS.
