Windows Phone Thoughts: Dell Axim X50's Lethal Cradle?

There's a worrying report over at Aximsite that 15% of Dell Axim 50's sold to Aximsite users since October exhibit problems related to their cradles. The figure is taken from an Aximsite poll with just over 200 responses. The cradles are shorting and causing either spontaneous reboots or, in many cases, burned out USB controllers on the motherboards of the host computers. Apparently some folks have had 2 consecutive motherboards rendered non-functional as a result of the problem. It appears that connecting the cradle to a powered hub may provide protection to the motherboard. Dell has not as yet commented on the issue. Have you guys had any similar problems with your X50 cradles or is everything just ticking over as expected?
