While there are many positive stories about Macs on the internet, I wonder how close to reality that is. I only have one experience - a 3 month old Macbook's USB ports all stopped working. I went into the nearest Apple store and they said it had "water damage". There was no sign of water damage anywhere around the ports, and when I opened up the laptop there was no sign inside. When I asked how they knew, I was told they "had a method of testing", which they were not going to share with me, and that was that.
