So do y'all keep your docks hidden or visible? What's the reason? I just turned mine off because I wanted to see how it looked. Right now, I'm likin' the full-screen Safari and the big iTunes and iPhoto windows but I also like how the dock balances out the screen. Not sure how I'm gonna keep it. What's your take? FWIW, I'm on a 15" MBP so screen space is not limited (like a 12" PB or 13" MB) but it's certainly not as plentiful as a 17" MBP or 24" iMac and certainly not a 30" ACD.
