Er.. if u haf to go through so much trouble for the MB, Y don't u just get something else? *grins*  Y buy something that'll make u become slave to it? 

@allvin,
There's no need to get an Apple of it's so troublesome.  There's so many other kind of notebooks out there - no need to just choose from range of available Apple products.  If it doesn't suit ur needs, it doesn't suit ur need. Y change ur need to make the product suit it.. it's just not right.. not right ! *shakes head*

@tinkerbel

Yes it's a color preferences and also because it look more 'cool'.

Look like the Black & White both sharing pro & cons regarding smudges, get dirty. So the main thing is just be careful when using it regardless it's a White or Black right? Always wipe it after use, wash hand before use it etc.
But White because it have a smoother surface, it more prone to get scratches even though you're already be extra careful with it.
