Command-line commandos are rejoicing at the ability to place Linux on the iPhone. The Mac|Life staff is excited about streaming Karate Kid to their iPhones. Plus, we wonder how great keynotes would be if they were under the sea.

Another holiday song is chosen for our weekly, "Keep or Delete." Each week we download and review the free iTunes song of the week and decide whether we're going to keep or delete the file. This week's artist:

Melissa Etheridge - Christmas in America

Don't forget, the Mac|Life staff would love to hear your thoughts, comments and ideas for the new podcast. Just leave a message on the Mac|Live question/comment line: (877) 404-1337, extension 622. Please limit the length of your messages to 1 minute max. We'll review these calls each week and feature our favorites, along with responses, on that week's podcast.
