So both my friend and I are students at Berklee College of Music in Boston. At the school everyone is required to have a Mac that meets certain specs when they come. The school distributes the most current model be it PowerBook or MacBook Pro depending on when your first semester is. When we started going here the last gen 15" PB was what was being distributed. I have never had any problems with mine that weren't acknowledged by Apple and cleared up immediately. As a matter of fact I just replaced the PB as #1 with my new MBP (love it) this past sunday. My friend on the other hand has had a whole handful of issues with his PB. about 5 batteries or power controllers 3 logic boards, memory slot problems issues with the computer sleeping randomly. Basically you name any problem there ever was with the PB's and he's had them twice. So he had another battery problem yesterday and got fed up and called Apple Care. He explained that he had a case number from all these other problems which they acknowledged and within 5 minutes they were taking his info down for where to ship a brand new 2.4 MBP. They said to him that they "didn't want him to look back on college and think of how apple never cleared up all the issues with his laptop." How awesome is that! After almost 4 years of good use with this PB he's now getting a brand new MBP for free. Hopefully this one will be problem free.
After they cleared up the problems I had with my MBP in a prompt and extremely courteous manner I can yet again say I sure do love Apple Care and it is worth every penny.
