I get the 6-tuner thing (or 4). Other advantages are the RF remote and built-in wifi. I have a 2-year old Premiere with an upgraded hard drive. The dual-purpose is usually fine for my family, although 4 would be nice. We don't ever *plan* on taping over-the-air again, but we'd lose that with the Roamio, right? I'd like to be able to stream to my Android. Tivo Stream might do that soon? I have a Premiere and a Series 3 (both lifetime, not using the Series 3). Wondering if I should sell both and get a Roamio or get a Mini or a TiVo Stream. Thoughts?
