I've been using it since it came out more than a year and a half ago. There are several threads here with some of my experiences and also other users'. Overall, I'd say it was the most reliable deck I've used (Sony M1 DAT, Edirol R-01, Sony D-1) in having less equipment or operator error, though there were some issues, and these required shipment back to Switzerland to fix. Mostly I use it with DPA 4060s and a DPA MMA6000 preamp into the line-in, but I've also done mic-in with Sanken CO tiny mics, with real mics and phantom power, but I've only played around with the digital-in.
If you get one, make sure it's upgraded to the latest firmware with the programming fix to enable tc, that has to be done in Switzerland.
