Not just Dell
I can assure you that very similar problems did indeed trouble HP.
Back in the late 80's and early 90's there were regular call outs to a certain high end salon in central London. Their keyboards started to do strange things once a critical amount of hair had accumulated inside them (all those tiny snips of cut hair floating around have to go somewhere.....).
After several keyboard replacements it was mutually agreed that those flexible jelly keyboard spill covers that could be typed through would be a sensible investment. We never had to visit them again.
