Chart of the day: Christmas messages from new tablets by Philip Elmer-DeWitt @FortuneMagazine December 26, 2012, 10:14 PM EDT E-mail Tweet Facebook Google Plus Linkedin Share icons Click to enlarge. FORTUNE — I can’t vouch for the accuracy of the information in this chart. The nominal source — A.X. Ian — describes himself on Twitter and other venues as “Purveyor of pseudo-random ideas. Information massage therapist. Always prolific, seldom profound.” But the ratios square with other signs we’ve been seeing — including store traffic — and bode better for the holiday sales of Apple’s AAPL tablet computers than for Amazon’s AMZN , Google’s GOOG or Microsoft’s MSFT .
