Title ask what I would like to address.
First off, I have no problem playing the content on my iDevices with what comes with openSuse, but the backups are important to me.

But iPad and iPod backups need to be made. I would like to do it from within openSuse without having to start Windows first just to make backups.
Not sure if a 32bit version of iTunes will do the job, but have to assume it will.

I looked at some documentation for PlayOnLinux, and it addresses 'playing games' but doesn't tell me if it will handle iTunes.
TIA Bill L
