anyone else get electrocuted using the 1.33 powerbook?? i'm now on my 2nd week of using it and i get electrocuted every 5 minutes or so. no fun. i've turned to using wrist pads to separate my wrist from the metal surface... but every so often i touch it and get zapped. it's not like a big shock, but it's definitely more painful than static! is this a problem?
