I thought on all Android phones that apps have to be on internal memory.

Expandable memory and replaceable battery were the main reasons I went with an S3 for my last upgrade.

I will say that I don't know anyone who has had to send an Apple device back for a new battery. My mom has a 1st generation iPad that is in constant use for the past 3 years and it is still fine.
