I wasn't aware that any 921 ever had a firewire port (none of the ones that I've seen did). I wondering if even the JVC HM-DSR100 had a firewire output.
I guess it comes down to what's important. Lack of promised support for a format that never really got out of the gates or reaching anywhere near the "up to 100" HD national channels (which was originally an unqualified 100 channels) that D* promised for 2007.
Perhaps your argument is more akin to D*'s failure to deliver on the "massive gaming league" that was promised at the 2006 CES. Maybe it was DIRECT Date. I can't remember.
