IIRC at the time, Flash lite powered or existed on many more mobile phones than did iOS. Neat stuff to read into the history of. Many of the things in this letter were true, but Apple itself was holding back some things. iOS had it's own battery management issues at this time (even though it was 1-2 generations ahead of Android power management). Cutting to the bone of power management has paid dividends for Apple, the iPhone generally manages power much better than any Android phone I use. The latest Nexus phones from Google started to change that drastically and I hope that continues.
