I have the best son. Patrick Scoble loaded iOS 7 beta 2 on my iPad Mini. So far I've already found a few bugs (the Google+ app doesn't show me some comments, for instance). But my life hasn't changed like how it did when Everything.me got loaded on my Android-based phone.
If you want to try it, I'd say don't. Not that big a deal and you'll have to live with lots of bugs (my son can crash some apps instantly just by pushing a button, for instance). If you are willing to put up with the pain (are a developer who needs to fix the bugs, for instance) then I'd say OK but you should know what you are getting into.
