I use WiiMC on my Wii for my kids' movies, and I install the games to a USB hard drive so my kids don't ruin the discs (and because I'm too lazy to get up and eject them).
I've just started programming classes, so soon I hope to start making my own Wii (and Android, Xbox 360, and PS3) programs. I love Nintendo, but I hope the WiiU is hacked as easily at the Wii, because there could be some amazing, amazing stuff for that console. I do hope that if the console is hacked, that you cannot go online with it, however, and even if it blocks you from playing actual games, that would be fine too.
