Thought I'd bring this to the attention of anyone out there who might be as thoughtless as I am. I happened to be working on my Macbook Pro tonight and also had my iPad 2 out as well. Without thinking i laid my iPad down on top of my open Macbook and was surprised as the Macbook went dark for a second. I was thinking I had covered up a light sensor and still without thinking I put the iPad back down to see if it would do it again but this time my Macbook restarted on it's own and suddenly it dawned on me that i had been setting a powerful magnet down on top of my hard drive. So far I haven't run into any corruption or data loss but I haven't actually done much on my Macbook yet. Only time will tell if I made a major blunder or got off easy.
