It's still good news to know that open-source software allowing current 
fanless integrated motherboards to decode HDTV at ~10% CPU is on its way...

Going from 87% of 2 cores, to ~10% of an entry level CPU is good, 
specially when the load is taken care of by existing chips.
I'd like to have full-HDTV on a single x86 mini-ITX board. I'm now 
seeing this will happen soon enough, and I'll wait until then before I 
spend money on new hardware.
