My experience was horrid (with 10Mbps connection). Tried two different machines and finally installed Chrome and it was better but not good. As it is now when I left home I was on the 2nd file of X2. I'm downloading (parts 3 and 4) here at work (T1 connection) with Chrome and it is still about 30 minutes per.
Very disappointing experience, will go with the boxed discs next time.
