I'm using Windows 7 Home and the lastest iTunes version. My laptop has some problems, I'm afraid it's even going to break down, and I intend to reinstall Windows. My library is currently syncing with about 5 - 6 iDevices. So I'm gonna back up all apps and music and restore it after reinstalling Windows. But I assume that when connecting my iPhones or iPad back to the laptop, iTunes will consider them as already synced with other computer right? So it will ask me to erase all data in order to sync with "new computer". The music is fine but if that's the case then will data in apps and all backups be lost?
