Yeah just as they said, ipad is a trademark and you never want to have a trademark in your domain name. Even so these domains are dot nets, which usually indicates the dot com is taken. A dot net will always be worth significantly less than a dot com. Also you have to look at the order of the the words in those domains. Freeipadapps.net or freeipadgames.net makes a lot more sense. Either way try and stay away from the TM's. Hope this helps.
