Amazingly for once, I agree with Gruber about the report being weird - but not with his reasoning. What I don't understand is why look at a time window a significant portion of for which the primary OS under consideration (Android) didn't even exist on tablets. The Android tablet ecosystem effectively only came to market in a meaningful way in April(and even then it took several months more to release world-wide). Why would someone make a report in which half the considered time period is more or less irrelevant?
