I was so glad when Apple went aluminum on the iMac and did away with the white iMac, likewise for the MacBook though the entry level is still available, which is fine. I didn't buy an iMac until the first aluminum edition.
But I just don't get the clamor for the white iPhone. Or people going nuts over a white iPad. Sure it might look really "clean" but I think in the long run it is a novelty and getting a white iPhone or iPad is a mistake.
