Hi @tamu_bu, thanks for weighing in!
Though I am a bit biased (being the product manager for the iPhone BETA program), my viewpoint is no, our pursuit of iPhone will not further slow the release of Android devices.
To expand on that a little: every company must juggle competing priorities with the resources available to make that “to-do list” a reality. Some priorities are in direct competition with others, some slightly overlap, and some are totally silo-ed. Fortunately for us, iPhone and Android fall somewhere between “slight overlap” and “totally silo-ed.”
iPhone and Android share a good bit of foundational service architecture (so one change would apply to both). And in the areas that they deviate, we have different teams (the iPhone app and Android app are developed by different teams, for example), or level of internal effort is not the same (we don’t carry iPhone hardware currently so that allows full allocation of hardware acquisition to be focused on Android).
Excellent question! I hope I provided a full answer, and please let me know if you have any follow-up questions.
