Overall, I think the MT will work for a lot of people; and if M-Audio comes through with the firmware changes, I might even say it'll work for most people. However, I sent mine back.
My intended purpose for the MT was as a 2-channel 24/96 backup unit (digi in), not as a primary recording device. I think the SD722, or more likely the new Tascam CF recorder, would be more appropriate for what I'm trying to do. The MT is still pretty neat for what it can do; but I couldn't foresee many instances where I'd be using it. I decided that the $$ could be applied to something I would use a lot...like a new set of monitors!
