My wife had an iPad for a year and synced to our computer with no problem.  I recently received an ipad2 and when I tried to sync using separate apple and iTunes passwords, under her computer user name, it appears I over-road her account and synced all her apps with my apps on my iPad.  I then set myself up as a new user on our computer and tried to sync.  I now get the error that my iPad is synced to another library.  How can I start over without erasing all my data on the iPad?

Answer 1

Go back to her login.  Unless you deliberately erased apps, they should all be there, both yours and hers!  Then, you need to set up each iPad separately.  You will notice that they have separate names for that very purpose.
There is no problem with multiple Apple IDs on the same iTunes on the same computer except...  Apps are permanently associated with the ID that was originally used to obtain them.  If you choose to update an app from inside iTunes and you're logged into the "wrong" ID, you must log out and back in again.
On the bright side, you can configure either or both iPads to sync with apps and music and movies, etc. from either or both IDs.  Further, if you choose to update the apps from the iPads themselves, there is no need to log out/in.  The device handles that.  All you need is the correct password.  In my case, I use the same password for both IDs to make things easier.
