When did double-shot keytops disappear?

Zane H. Healy wrote: I remember my father acquiring one new about a year ago from Staples (UK office supply store, if you don't have them overseas). IIRC it was made by Packard Bell. It was silver, and it stayed silver for about two weeks of use - after which the silver had worn off the most commonly used keys (key legends too of course) and exposed the black plastic underneath. I think that has to get my vote for "most unfit for purpose product" that I've seen in a good ten years. Incidentally, he lived with it for six months then bought another, identical one. It did exactly the same thing over the next two weeks, so PB obviously never got around to fixing them. (he's a bit of a technophobe is my dad, so he'll tend to stick with the same broken product line in preference to 'risking' an alternative that might somehow hook up differently :) cheers Jules
