Just remember to hold on tight to the Wii controller and USE THE HAND STRAP.. I work for an Electronics Manufacturer, and we have had several issues where the controller flew out and hit the TV screen, causing either a cracked screen, (on projection sets) or a broken LCD panel (on direct view LCD. flat screens)
There was an issue with the hand straps breaking and Nintendo offered a stronger strap on previous models. New ones should already have this. Problem is, some people still dont use the hand strap, and when you accidentally let go, the controller can do some damage to whatever it hits.
Obviously this is not covered under the manufacturers warranty, and I dont know of anyone that has been able to get Nintendo to cover the damage as of yet.
My $.02 worth..
