Makes me laugh
the old apple vs pc debate flies off again. Personally speaking, the mac is just a pc now, it uses the same parts as a pc and uses a unix based os. Shove a good linux distro on a pc and you have much the same but better specced and half the price. Your paying for a brand, wish people would realise it, apple is no better or worse than a pc (although the apple is using older and cheaper parts which probably do run slower than a pc you can buy right now off the shelf).
@simon gardener: I think you mean if you are thinking about buying a macbook then this is the way to go, if you want a free ipod then I think your cheaper just buying one :p
@John Tuffen: If your xp pc is taking this long to boot I think you might want to take a look at it, I've never had a pc (windows xp or vista or anything else) that takes longer than a minute to boot unless of course its filled with spyware/viruses. Maybe time for a cleanup? :)
