I use my Elite for the Mini, simply so I can have all six tuners free on the Pro. I use the Pro as my primary TiVo, and having all six tuners free makes recording decisions mostly concern-free.
I use the Elite as a glorified Mini. While I do record a few shows on it, it's in the bedroom, and I use it to stream or XFR recordings from the Pro.
