The 13" came yesterday, and all I can say is that if anybody wants a small form factor powerhouse, max out a 13" and you won't look back...Even if you have used a retina IPad you are in for a shock when you turn the rMBP on...pin sharp text, and depth of detail make this exactly what I wanted, and I can honestly say that I won't need the whole week to decide....It won't be going back for a 15". I don't like the new MagSafe cable, but nobody else seems to either...I can see why they did it...it's likely that the cable will stay straight, with less fails due to fraying.....the cooling vents are large, and I plan on a weekly brush out there...haven't yet thrown anything heavy at it, but I will today.
I guess my Apple Girl has won her bet, which means I will send chocolates! It's a really fantastic machine.
