Hi All, I just bought the new iBook yesterday, and I was curious to see whether people had any input on how rugged this laptop really is. It feels very solid, but has anyone had any problems with it? I also noticed that the escape key feels like a loose tooth -- is this a common issue with the iBooks? If for some reason it falls off, can Apple replace it after the 90 day warranty period (I don't have AppleCare). Thanks in advance for your help!
