Hi guys, serious rookie apple user alert! I'm jumping ship from windows laptop to Macbook Air and my MBA is arriving tomorrow and I have no idea what to do, part of the fun! I have never used an apple. Anyway I was just wondering if the battery was good to go when it arrives or if I had to charge the macbook air for a certain amount of time before using to make sure I get the most from the machine? Only reason I ask is that in the past I've had to do that with mobiles. Excited!! Thanks Warnie.
