Photostream also just has pics no videos.

If you save a number of videos on the phone, backing
it up to icloud will quickly go over your limt?
 
Perhaps its good for "find my iphone" as well.

I wonder if just leaving that on is a large drain on battery life?
 
Google+ Photo Backup?

I am awaiting delivery of my 4S in a week or so :) Coming from the Android platform one of the nice features is that the Google+ app will perform "instant uploads" of any photos or videos you take on your phone. It uploads the photos to Picasa (an unlimited amount for an unlimited time). Does the iOS Google+ also perform the photo uploads? If it does, it seems like a good tool for people to consider using for their cloud strategy.
