Worth it for the charts alone.
Update: But their chart on Apple’s revenue-by-product contains an error: for the just-completed Q1 2011, they used the iPad’s unit sales (7.3 million) rather than its revenue ($4.6 billion). So the iPad hasn’t yet passed the Mac in terms of revenue, but probably will within the next quarter or two. (Source: Apple’s SEC filing.)
Update 2: And just like that, a few minutes later, Macworld has fixed the chart in question.
