iPhone vs. Android
A very interesting statistic. Android is now 75% of the market as it pertains to device market share, but the Safari browser on the tablet and cellphones has a market share of 65%. See the tables below:

So taking into account the tablets, and the use of the browsers, we see that Android has a long road ahead of it to catch up with the tablets.
I just thought this was interesting.
