2.  IPhone came out first and had more time to develop. (3G)  Also was developed using OS-X  Android was started as a mobile device OS acquired by google. (2005)  Came out in 2007 on poorer hardware (G1)

3.  IPhone is locked down only controlled by apple  Apple changes the hardware and has control over any of the software to go along with it  Allowing a cleaner view of versions  Android is made portable for any hardware you wish to try to make it work on.  The base OS version at the time is what is modified by phone makers  No clear versions for OS to develop for!!  Advantage: Android

4.  Apple needs a Mac  Android needs an x86 processor  Other than that they both have debuggers, emulators, and a decent SDK  Advantage: push

5.  IPhone has portability if you have developed for the OS-X  Android if you know Java you could easily port. Although no Java Standard Edition support, just a subset  Advantage: push

6.  IPhone polices all of the applications that are submitted  More dedicated developers  Android allows all users to develop and release applications  Each app is in its own VM  Advantage: IPhone

7.  All development capability seems even  Ability to change OS for your own use on any hardware  All-in-one systems is the future
