Thanks for the feedback. I think we will both be excited to play with our new "toys". I will probably do that this weekend and do without for a couple weeks. Absence makes the heart grow fonder and all that.
Yes.
Remember, anything you have purchased can be redownloaded..but things that are created by apps, even games, have to be backed up. iTunes won't back us songs from your iTunes library, so stuff like that usually has to be restored. I used to transfer PDFs to iBooks to read them...last time I did a backup/restores, none of those PDFs were backed up by iBooks. Luckily, I backed up my iPad 3 and restored to my iPad mini, so I didn't lose anything...but you could lose something since you are going to a new devices from an old one...
Thinking that out, I suggest you back up your iPad 3, keep it, restore to your iPad 4, inspect all your stuff, and only after you have confirmed that everything got transferred and you are not missing anything you want, only then should you reset your iPad 3 and hand it over to your son. The extra effort will ensure you don't lose anything you want. You can go to Apple's website and look up info about backup and restore to get a better understanding...but it seems rather complex to me. It is a good idea to spend time when you can learning the ins and outs of backup and restore. Getting a new iPad 4 and handing over the iPad 3 (which is still new) is an excellent opportunity to get a good look into how it works.
