The guy simply bought a lemon. It happens. It says absolutely nothing about the rest of the Mac line (as I've had several Macs). While I have had some frustrating experiences, they've been pretty rare; like 3 in over a decade.
When I did have serious Mac problems, it always ended up being the hardware; something easily replaced, like bad RAM. It says something when you learn to suspect hardware problems because the OS itself is so solid.
