I am a potential convert to Mac. However, I am also a person that likes to have the full information on a system. I would really like to know what people DONT like about their macs. I have heard quite a bit about what people like about them and I have done quite a bit of research. As background Im a senior software architect and O'Reilly author so I know my way around computers; feel free to spit out the technical terminology. I have used windows and several variants of unix heavily but havent used macs since the mac classic days. Lets hear the dirty laundry =) How often does it crash? How often do you feel compelled to reinstall the system? How do your non-computer professional family members handle OS X? Do you still keep a Windows machine around and why? What annoys you the most? Would you ever switch back? Would you quit a job that wanted to make you switch back? What OS did you use before OS X (non Apple OSs) ? What is your profession; or area of study if a student?
