Lots of people do seem to have experienced that problem, although my iBook 500's mic works fine. I know of no explanation for why so many are affected, and mine is not.g.money said:maybe apple will get off their ass and fix the stupid bug in .3.4 that de-activates iBook500's internal mic. From what I gather in the apple discussion forums, the problem is only limited to this model.
Of course, being nearly 3 years old, I guess my beautiful icebook is considered irrelevant to apple (can you tell I'm a little frustrated?)
I'm up for any bugfixes and features Apple chooses to throw our way. I wouldn't rule out home-on-iPod or other minor new features, Apple's done quiet new features in point releases before (though it doesn't happen often).
