Anyway I've just noticed that the usb connector is very unstable. If I lift the wire from the table (or touch it in an upward direction really) the board will disconnect. (Power failure)
Got my Plus yesterday and had the same problem. Solved it by squeezing the metal shield of the usb connector on the netduino a bit, so that the plug fits tightly.
Of course you have to be cautious when doing that.

I could be the cable, yes. We tried pluggin it (the cable) into a HTC phone, which showed the same symptoms. (Either that or we have bad HTC as well.) I've ordered a new wire.
The MicroUSB cables which we're giving away with the Netduinos as a free promotion are tested by the factory; they're the only part not tested by us...
We expect to see few failures of the free cables in the field. So far reports are <0.1%, but even one bad cable makes us sad

The USB connector on Netduino is Micro USB (the replacement for Mini USB). It is designed to remedy many of the issues of the old Mini USB standard. It supports 10,000 insertion cycles and has a locking mechanism.I just got the netduino board, set it up, compiled and ran blink, moved the board by the usb cable (like I do with my arduino boards all the time), broke loose the mini usb connector and threw the whole works in the bin; in about that order.
I have been using arduinos in all kinds of rough and tough environments and their type b connectors 'never' fail. Mini a and b are not strong enough. Please consider a redesign. I know type b connectors are clunky looking cans with a big footprint, but they will stand the strain.
We used a special Micro USB B part which is reinforced and soldered into the PCB--so that it's really hard to break off the connector. Unlike many of the 2-4 point surface-mount-soldered Mini/Micro USB connectors.
While our test process verifies that the USB connector is attached, it is possible for a weak bond to slip through from time to time. It sounds like this may have been the case with your Netduino.
Your Netduino is covered by a 30-day warranty. If the Micro-USB receptacle simply popped off the unit, that is certainly covered by the warranty. Please PM me and I'll get you instructions for replacement.
Sorry for the troubles, kenn!
