(Snip) *** One needs to look at the total numbers to determine the group percentages, unless each company had the same number of laptops in the survey. So HP may have had a 25% failure rate, but that does not mean that 7500 of the 30,000 laptops were theirs. -- Richard Bonner http://www.chebucto.ca/~ak621/DOS/

I would assume that HP probably had the highest number of units in the survey. Apple would probably a low total sample, as most Mac owners would opt for Apple Care for an extended warranty. Another problem I have with this survey is, what constitutes a failure. Is it total boot failure or things like stuck pixels, detached keycaps, power adapter problems, etc? You could have a laptop with top rated internal components, but with a flimsy casing or keyboard. Also, some makes will tend to be babied by their owners. Sony and Apple probably fall into this bracket. Any relation to Dan Bonner?
