My buddy and podcasting cohort Manton Reece has announced the release of Wii Transfer 2.6. His application is apparently a very cool means of interfacing content from your Mac over to your Nintendo Wii. I wish I had more hands-on experience, but unfortunately I do not yet have a Wii of my own to play with!
If you love your Wii and your Mac, then this app is probably worth taking a look at. Congratulations, Manton, for finally shipping :)
