Where does your Mac get 2 minutes 40 seconds? My father's Mac Mini with a 1.4 G4 processor takes less than 30 seconds to boot up. I 'm trying skype right now and it takes less than 10 seconds on a cold start on my Linux box with a 1.7Ghz Pentium M. Both of these machines have slower specs than the one you stated. Does that mean Office takes a whopping 2 minutes to start?
No - I don't believe so.
Every post except mine after my post regarding this on this thread is apparently comparing Apples with oranges. I'm not talking about Linux (wth should I talk about Linux after my initial post on this matter?), old machines, etc. I'm talking about comparing a current Mac with a current Windows / Vista PC - for real. i.e. one which you actually own.
I chose Skype as the main startup item because a) I use it and b) it's a cross-platform application that has an adverse effect on startup time on both platforms so that I could get a 'real' time on how long a reasonably loaded-up system would take to be usable.
I booted up the MBP, started Word and waited until a) everything had come up and b) I could do stuff in Word. On the Mac, this happened to be almost the same time - the 2:50 I mentioned. All of the machines I used here have 2Gb of RAM.
Under Vista, the time to Word being available to use and full machine start-up including Skype varied a lot. Office was responsive almost immediately after logging in, but it took a while after logging on for everything else to initialise. The Dell time you see is the full startup time, which is still a minute short of a Macbook Pro with very similar hardware. The Sony time is the time it took for Word to be available - which is as I said above a lot shorter than the full boot-up time, and qualified in my previous post saying Skype wasn't installed.
