Internet polls are fun but rubbish. Formal surveys conducted by so-called experts aren’t much better. If you disagree, consider this: A poll I conducted for Betanews asking “How would you identify yourself as a computer user?” puts more than 25 percent of respondents as Linux PC users and less than 61 percent as Windows PC users. Do you believe that? I don’t. But I do believe, as early results indicated, that there are more Betanews readers identifying themselves as Linux PC users than Macheads. But more than one-quarter are Linux users? Perhaps in some alternative universe, but not this one.
