I am the proud owner of 2 iBooks (G4). One of them died once with a faulty logic board. The other died 3 times with exactly the same problem: defective logic board. Statistically seen this can not be coincidence. When will Apple admit the problem?

My daughter and other students have had the same thing happen to their iBook G4. That is why I was browsing the internet, I was trying to get some info on what may have happened and came across this article. I am not impressed that I opted to buy the iBook from the school and they are not even going to admit to a defect or repair the problem. My daughter just started college without a laptop!!
