Here in Bellingham, WA, starting soon after 8:00 AM, I downloaded it at an average I'd estimate at about 1.7 MBps, or over 13 Mbps. I have Comcast's 12 Mbps "Performance" package for $24.95, and IMO they've exceeded their commitment. Apple has astounded me by serving it at this speed. Very pleased with both companies. It's rebooted and is installing right now on my 27" late 2009 i7 iMac.
