For what it's worth, I got an MBP from work and it's power supply has an annoying coil whine/hum. I've looked online and it is common enough I haven't bothered to ask for a replacement. Quality issues like that exist among all manufacturers. Likewise with the software side. OSX still has bugs and I still waste time working around behaviors like in Windows or Linux. There are definitely benefits to it but there are drawbacks too.
