Yes, I read someone explain multiple tablos, at first it sounded flubbed up. Then I guess it depended on your situation. Multi-user house with independent could be a good things. But I bet for most, having access to each device from one point would be less confusing. How to keep track which device records which shows. Sure, manually use one for channels X - XX and the other for XXX - XXXX (Xs used figuratively), but that’s wide open to (human) error.
It would be nice as a tablo “what-ever” device enhancement.
