Well, it can survive a hard fall of about 4 feet, I know that for sure. I own a G3 iBook without wireless (I'm broke) so I always have a 100 foot ethernet cord trailing behind me. Somehow, as I was walking from one room to another, I got tangled up in it, did a funny little twirly-dance, practically threw the iBook out of my way (if I would have landed on it there would surely be no chance of survival) and fell to the ground face first (ouch). The iBook landed hard on its left side. It was powered on, as a matter of fact I was browsing this forum. The sound it made on contact was horrible to say the least. But I'll be damned...so far not a thing wrong with it! When I say it took a hard hit I mean it REALLY took a hard hit. When I picked it up off the floor I wasn't breathing...it felt like my heart had stopped. The screen was black, all was quiet...for about 3 seconds. All of a sudden the screen lit up and it was right where I left it. I just had to reconnect to the internet and I was rolling again. Just wanted to share that with everyone, for I am blown away that the thing isn't dead. If a moose like me can't kill this iBook it is one hardy machine
