Thanks - does this mean that there is no way to switch off the back up process? i.e. is the choice simply one of either a backup to iCloud, or back up to my PC? I'd prefer to be able to switch off the backup altogether, and then just manually backup at my discretion ...
Yes, as others has stated, you can do this, but be warned that as soon as you choose to do this, you are then the responsible party if all of your content is lost and you do not have a current backup. It is amazing to see how many people post on these forums that Apple is irresponsible because they didn't do a backup and lost everything, so when I ready your post, I think of them.
Another point I would like to make for you. If you keep your device synced regularly, the backups should process quickly. If you let long periods go between backups they take longer to run. I remember some people needing to give their iPhones several hours to complete the backup when they upgraded from iOS 4 -> iOS 5 because they kept canceling the backups...
