Oh, I won't be surprised.
But, I also think that it's nothing more than an educated guess based solely on the iMac color options.
And if anyone cares, purple—yes,
purple—is the color everyone seems to want.
Purple!
Yep.
Of all our pre-orders, 90% are for purple. And, no, I have no idea.
Edit: Just checked, and the only other preorder is for silver.
*Disclosure*: Yes, I know people are ordering all of the other colors, but it's just weird that for us it's all about the purple.
