Can I assume that using the initial prompt at startup to import data, applications and settings from an 11" Macbook Air will work without problems when we get the new iMac 27"? It is coming in a few days, just got a notice from Apple. I have a clone of the 11" MacBook Air, and was planning on using that connected by USB. It is a USB 2 drive, a little slow maybe but it should work. Right?
