I'm particularly sensitive to magnetic fields, and get a headache just from using cell phones - a bona fide, wave pressure migraine just from having an active cell phone operating near my head/ears.
But it is a good idea to note that EMI and RFI are related but different, and that a cell phone in send mode vs receive mode have differing levels of both (EMI and RFI)
Thanks for an "eye opening" post!
I will note that as someone who is an early adoptor of both (my first cell phone was the military style "shoulder field kits" and I've used them regularly since...) I've never had a problem with magnetized watches.
Of course, I may not have as much experience with watches as some others...
Oh, and my laptop speakers are at the top, near the screen hinge, not at the palm rest, bottom, of my Toshiba.
