So in the last 9 years, 5 have had major hardware announcements? Hardly seems like a trend.

[cosmojg]

5/9 is a majority of conferences. I think OP made a fair assumption.

[philwelch]

5/9 is also approximately half, and 5/10 is exactly half.

[yborg]

So, by definition, most of them? Seems like a trend.

[rconti]

Well, now, 5 of the last 10.

and more recently, 1 of the last 5.

[notatoad]

Its currently 2018. Going back to 2009 = 9 years

[rconti]

Right, but 10 if you're inclusive.

[notatoad]

sorry, i'm still not understanding how that works. from WWDC '09 to WWDC '18, inclusive of '09 and '18, is 9 events.

[rconti]

It's not.
