Few things to add:
- the included version of TMT isn't the full version, it doesn't do BR/HDDVD playback
- even the new HW version (D2) has overheating problems; I have to put mine vertical to ensure 100% uptime (there are vents on the bottom)
- the top lights up on D2 hardware (my original C2 unit did not)
That said, I think this is the best product to come to HTPC users in a very, very long time.
