Hi, im new to this forum, and also this is the firs mac i've had, and was just wondering if anyone has had issues with the new 13"s audio? I've had mine for about a week now, and hadn't noticed anything up until today, but only because i had been using headphones most of the time. When i play something on the laptop using the built in speakers, i have noticed a fair amount of vibration noises when it is turned up high. I don't know if its a fault though, or whether it's to be expected for the speakers on a 13" laptop? Also, just as a side note, when i got my laptop, the casing was in perfect condition, as was the wrapping on the laptop, but when i opened it, there was a 1cm diameter sized blob of mud on the side of it, crazy as it sounds. It didnt bother me too much cos i was able to get rid of it without leaving any marks, but it did surprise me. Anyone else had similar issues? Anyway aside from these small issues, i am loving the macbook pro, and I'm so glad to be leaving my chunky sony vaio behind!
