Of all the things people like to bitch and moan about the Wii, its lack of storage is right up there. This easy-to-follow tutorial, however, may render that argument a moot point.
Using the Wii's Homebrew Channel, a USB 2.0 hard drive and a few files, anyone feeling mildly adventurous (really, this doesn't sound that hard) can copy all their Wii games over onto the HDD, then run them straight off the same device. No more discs, no more disc-swapping.
Convenient! Shame the Xbox 360's recent "install" option didn't let you go this far.
