I have pretty much decided to come back after my commitment ends, but I was wondering... Is there a real difference in the Roamio vs Premeire UI. I know the Roamy is faster but the price is the premier is significantly less. I asked Tivo the question through chat and all they gave me were hardware specs. Is there any difference in the UI itself? This question is especially for folks that have done the upgrade.... Can you articulate why its worth it? I am coming directly from dish. I imagine the speed of the premier will actually be faster than what we are currently using.
