tom.k: that is... ignorance...
You can't comparison present Mac and give it credit that hold Mac in past. Conteporary mac isn't priorited by graphical designer. This is just plain wrong. As well as optimisation etc.
From your standpoint, one should than add, than general unix would behave mutch better than windows or even Mac. Your comparison of booting is silly, this is heavilly influenced by installed programs, that start on startup. With so mutch spiderite, that comes preinstalled with windows, booting is hella slower, than in cleaned computer, be it on Mac, Unix or Windows.
The major difference between system is between it's users.
On windows, most of us behave as pigs.
On Mac, you would probably not touching anything.
On Unix, you would be probably experienced user, that tries to make it clean, or you don't touch anything.
Yeah, Windows and unix-based systems are different. Mac is different only in optimalization for it's hardware, it doesn't have to solve major problem of most machines -- drivers (which even't from hardware developer is quite often buggy).
Other code optimalization of system (apart of inherent unix so strong bash) cause minor differences.
