Here is what I mean, the colour of the light on screen, is affected by the lighting in 
the room, the computer is sitting in, so a room with oddball lighting like the pinky-
orange of sodum-vapour, or the odd colour of some florescents, can influence the 
colour balance of your work.  You can control this, at home, you can't always control 
the lighting in the field.  Mind you a good old fashioned Kodak grey card can do 
more for white-balance then anything else.  Simply flip the card over (the back is 
white), and tell the camera that the card is white, and let it's white balance figure it 
out.

Better keep a backup of your data, if it does get stolen, your not sunk.

It uses standard memory, most laptops do not, then again you pay more for a Mac 
in the first place.

I wouldn't colour balance in the field, so the laptop is just to review the shooting and 
store the image.  This isn't to say, you always need two computers, some people do 
carry a laptop, and then use the same computer to do everything else as well.  A 
good feature then is the ability to plug in a standard monitor, keyboard and mouse, 
to make working at home easier.
