The G1 was released in October of 2008, yet they still had 70% of the number of project releases that the iPhone had in 2008. 70% as many OSS projects in a quarter the number of months.

(Granted, the SDK was available for longer, but still very few people, developers included, actually had a phone; they were excited enough about it to develop apps solely on the emulator, without being able to actually use them until October.)
