We don't have any static problems, here in the UK. But then again, we have a 3 wire mains supply, so the piano is connected to earth at all times. The most common problem I have found with the cradle is the connection from the the mains cable to the adaptor.
Also, I've seen a few fried batteries (to the extent where the battery cover has buckled). This is due to the battery heating up if the PRC is left on the cradle for a long time. My advice is to charge the battery until it is full and then not to put the PRC back into the cradle until the battery is running low again.
BTW, my main concern during winter is underfloor heating systems. I had to fix a Mark IV recently and had to get up from under the piano every 5 minutes to let my back cool down. Not too good for the piano either, I would have thought - it needed recalibrating and it was seriously out of tune.
