Plus you must factor in the hours you need to reformat and reinstall software when you buy a new PC. Takes hours to get rid of all that crapware and a million updates! With a new Mac I get my clone drive ready before I buy. Once I'm home I clone to the new mac and have a beer or 2 while I wait. I'l never forgive microsoft for the 24 hours I lost trying to reinstall Vista on a computer. Even if i'm a walmart greeter making 10$ an hour, that is $240 of my time!
I mean what is this? By what you state here I'd say this is what people call apple fanboys sheep for, no offense (if that's even possible).
Get rid of the crapware? I mean, if you buy a new PC you won't have any software on it to begin with, except a few programs but they'll be deleted in a matter of seconds (obviously browsing to the place where you delete them could take a minute).
And all those updates, I mean, you can just have them download, no reason your computer shouldn't be usable while that is, and you ARE also able to clone your drive in windows.
