eNoodle, I believe Xybernaut has an office in Germany and sold the WebTD 375 under the name Atigo M, and think the Atigo T is the same as the WedDT 366.
FYI, there is no more Xybernaut.
I just powered on and checked each unit for the model number. Below is a list of the units I tested today. The S's are just the standard CE model, but my XPE model (it's slightly different) is also a DT366. I've been slowly selling off some of them to make room here.
Atigo L - DT370
Atigo M - DT375
Atigo T - DT368
Atigo S - DT366
