Just an observation: I believe I would strongly prefer a timeline, like
iPhone 3 ||||||||||||||||||||||||||||||||||
iPhone 4 |||||||||||||||||||||||||
Nexus one ||||||||||----||||-------
Other ph. ||||||||||||--------
This would make several things much clearer (e.g. what's the uptake of 2.3? Have Android manufacturers gotten better or worse?)Still, interesting.
EDIT: Just FYI, at 47 minutes this has 9 points.
