One problem with plugging into ship's power is a catastrophic surge or
spike as the alternator self-destructs might take out your handheld at

Ha! Excellent point! Now then, I wonder how many would buy a
modestly priced transient voltage protector for their expensive
GPSs, PDAs, laptops, CD/DVD players, XM radios, etc?
My little company could turn them out easy enough...
