So far so good in my first week with the new TiVo Roamio Plus. I felt like it was a waste of money to continue to pay Comcast a monthly fee for renting additional DVR boxes for other TVs in my apartment, so I thought I'd get a Slingbox so I can watch TV in bed.
After reading more about the Roamio, it encompasses everything I wanted from the Slingbox, plus more. With the Tivo app, I can actually download my DVR content to my devices (iPhone and iPad), I get the better DVR interface, the universal search where it shows me access to content across Netflix, Hulu, and Amazon (only one missing is Apple.)
Before I was using Apple TV, often running apps through my PS3, and now I think I'll use Tivo 95% of the time. I'll update more as I use it more.
