Learn from your competitors' mistakes. When Xbox 360 shipped with crippled downloading functionality, we were all over it -- for months. When the problem was eventually corrected with a spring update, we figured our suffering had ended. Enter PlayStation 3.
That Sony's new console lacks background downloading and a download queue is maddening. It represents an utter failure on Sony's part to use these past 12 months to orchestrate a console launch that exceeds the precedent set by Microsoft. Sure, a firmware update could fix this, but why is Sony launching with a feature that gamers deemed unacceptable a year ago?
Update: As noted in Comment #6, if cancelled, downloads can't be resumed later (file must be re-downloaded in its entirety).
