If you want to blame someone, blame the developers that do not utilize this function.

I don't think it will back up user data though so you will probably have to do that manually.
Thats what I did when I had my phone repaired. I got the phone back with factory settings and I put my account back on and it gave me all my apps back to my last save point.
This is why Titanium Backup is my #1 favorite Android app. Some people claim to have issues restoring apps and data but after 3+ years of very frequent use...It's the best way to restore app data. Gotta have root and need to know how to use it properly, but it works.
As far as Google backing up app data vs the developers...Google now is an example of how this should work. Small files, frequently backed up by one source would be fantastic. I bet you will see this in future versions of Android.
