Xfinity X1 is probably nothing more than a marketing name so they can 
bill us more for the service. :)  I've had plain vanilla Comcast service 
since moving into my home in 2006. The only issues I've had were signal 
leakage on VHF caused by poorly installed connectors on the coax, and 
noise from the electronics on the HF and VHF bands radiated either 
directly from electronics or common mode on interconnecting cables.

I have minimized the common mode component by using WiFi for nearly all 
of my interconnected equipment (computers, Apple TV, Roku, networked 
printer) and using serious ferrite chokes on all the connected cables.  
I run legal limit on all HF bands and 160M, but the closest antenna to 
the room where the cable modem is located is about 150 ft. I bought that 
cable modem in 2005. Results may be quite different for shorter 
separation from antennas and a newer cable modem. :)
