I bought my first iMac about 9 months ago along with Apple Care. I am not sure if it's a wise idea to try and keep the box for the unit as it's rather big. But then again the 27" iMac is rather big too. I have taken the iMac to the apple store once for the genius bar, and could see a benefit from that perspective, but it is a huge box and hard to store. I am wondering if keeping the shipping box is simply just something every mac owner does ?
