Query: CASIO PC unite experiences

I found this product to be useful but not reliable enough to take on overseas trips away from the computer that loads it. Every six months or so it spontaneously reboots or "hangs" depite sending back to local agent. This can be quite annoying. This manufacturer has a very nice idea that I like and I look forward to a new model as I cant live without a wrist reminder but it should be more stable than this version.
