I have my whole setup revolving around the Studio 18|24... It's excellent for recording but I use my big desktop rig to power Studio One and the 18|24... It's a hassle to have to turn on every time (yes even if it's sleeping) I just want to hear my guitar or synth. Pushing the single power button the 18|24 is the most desirable feature I can think of for my hardware setup.
Please implement passthrough on these devices if it's possible so I don't have to have a computer on everytime. Just enable hardware monitoring when the 18|24 is on and has no active USB connection.
