My download took about 4 hours last night but the Poser 8 Content zip wouldn't open.  I got an error message that the file was unusable and to redownload it.  I started it this morning before I left for work so hopefully by the time I get home it will be done and not have crashed part of the way through.

As for download speeds, while I watched it the speed fluctuated between 25 and 100 kbs on a 16MB connection.  I realize demand was high but SM should have anticipated this and made sure there servers could handle it better.
