I wont second it at all. Coz definitely a black paint job cant cost 150$ at all. And from the way I see things, this will very soon be changed. Apple definitely cant charge 150$ extra for black color forever. IMO by the year end it`ll be reduced to a much sensible 50$. or even less. So you are paying atleast 100$ extra just to make your MB look a little better? Only a fool wud pay 150$ for a black color.
Now before you start. Lemme clear that I was(and still am a lil bit) one of those FOOLS who really wanted a Black MB at any cost, even had the money but had to be satisfied with White in the end as I was left with no other option

.
But now with a White one in my lap, I m more than satisfied with the white color. There`s no way anyone can mistake it for a G4 iBook. It`s way too better than G4.
So all those of you who want to buy a Black MB for 150$ premium; I dont think nothing wrong with your idea. Black definitely is cool IMO. But white too is pretty good.
