No, you are old ;) (so am I) Magnets have never hurt computers. They were
bad for the floppy disks and hard drives that the data was stored on,
because the information on those is stored magnetically. Today's small
electronics use mostly electrical storage to store data, which is not
effected by magnets . Keep in mind that things with larger capacities, like
10-80G Media players, still use little hard drives and a strong magnetic
field can affect them. Wouldn't worry about magnetic catches on a case or
clasp though, unless it is strong enough to hold your Ipod/Zune to the
refrigerator. Magnets were bad for monitors because they were CRTs (Cathode
Ray Tubes) which used magnetic fields to bend streams of electrons. You
could magnetize the front of the screen which totally messed up the picture.
You had to have the TV guy de-Gauss the screen. Gauss is a measure of
magnetism. Today's little electronics tend to have LCD (Liquid Crystal
Display) screens which magnets don't affect. All the little Flash cards are
electrical, not magnetic storage, as mentioned above. They aren't effected
by magnetic field. I expect if you got a strong enough field, like in an MRI
you could cause issues, but it is pretty hard to generated that significant
a magnetic field without getting an electrical field with it, so it would be
hard to tell what did it if you had a problem. Even the metal detectors and
X-Rays at the airport aren't a problem for phones/PPCs with internal memory,
LCD screens and flash memory cards. My devices go through the X-Rays all the
time, with no problem in my jacket pockets.
