I use the motu monitor as a computer interface, as a rehearsal headphone mixer and as a life P.A. mixer for small gigs using wifi.
With the build in mixer (router) you can do anything. When it is setup like a home studio you kan use 2 pair of speakers with direct control/mute buttons in the front.
To use all the inputs i connect my focusrite peamp with a small ADAT cable. You can have 24 inputs with this monitor 8 and send 6 stereo mixes to the headphones.
Pro's:
A lot of in and outputs
Perfect sound, you chose the preamps you like
Build in headphone amps
Control over wifi
Contra's:
Mix software not that easy to do a life mix with laptop or tablet.
No midi
