My dock died! I put the Xoom on the dock last night to charge and saw this morning that it's still at 14% power. I tried repositioning, unplugging/replugging, etc. Thank goodness for that little pronged charger. Hmpf.
(Okay - not thrilled, but I'll see about exchanging it soon... I licked the prongy thing on the power cord and plugged it back into the dock base. Voila! Magic tongue? Perhaps.)
