Now even if there is no other difference I still am okay with the Bolt just so I can upscale my programs to 4K quality by just selecting the 4K resolution selection (yes, to me it's worth to price). I have no other way of upscaling on my TV to 4K even with my AVR. My AVR only upscales to 4K quality at 1080/24p resolution only. But I'm curious if there are any other advantages, I'd like to know. I did order one (a 1 TB) on eBay that's arriving on Monday with All-In service that I will use for OTA and I plan to give my Roamio to my mom which she could use with her cable.
