We used TiVo for years. It just never really got better.
What sealed the deal for us was that we could consolidate on Apple TV. Each TV has one Apple TV which has Tablo for OTA broadcasts, and Netflix, Amazon Prime, etc. for other content. No more switching inputs every time I turned on the TV.
Tablo’s UI is still rough. I really wish it the rough edges would get buffed off, but it’s fine for now.
