I just bought 7/2/2010 the 13" MBP started recording in garage band 8 tracks at once through an Maudio 26x26 interface. I just got a "DRIVE TOO SLOW" error last night. 5400 rpm drive. well now I want to know will the 7200 drive and more uphmm of the IMAC be a better platform? Bought into the Mac world so I did have issues... we'll see I guess first one in only a few days...Dont get me wrong I love the mac just wonder if i should exchange today. Help please asap!!!
