DJDarren, I'll tell you what's fucking mad.
I present the show using my MacBook Air. I took it off charge at 7 when I set everything up.
I've just done two hours of live radio on the battery, and exported the recorded show and there's still 55% left in the tank.
Also, I came off air 12 minutes ago, and it's already exported the file.
Apple might be shithouses, but they know how to make a good computer.
