I thought macs were magical, mystical machines that never ever have a single problem!
The only thing really mac about it is the OS, if you would open a Mac you will see loads of other well known brands inside them like Sony, Samsung and so on... You are probably talking about the old stuff running on Mac OS 9 or lower! At that point Mac was good.
I think about Mac not more as some PC parts screwed into a small white or aluminium casing with a large pricetag with MacOSX included and the possibility to install Windows on it.
I would only advice people to use the Mac if the software you like to use only runs under MacOSX.
