Attached to the post are some graphs from the past four years, to show actual and projected growth, yearly seasonality, and weekly frequency.
Note that the entire Mac OSX web experience now stands at 10.15%, whereas the entire Windows franchise declined to a recent low of 88.68%.
What is even more interesting is that MacIntel share grew from 6.51% to 7.19%, a difference of 0.68%.
Windows Vista instead grew from 20.45% to 21.12%, a difference of 0.67%. Taking this statistic at face value implies that in December more MacIntels were sold than Windows Vista machines. I am not counting on it, but this stuff looks good.
