Wal-Mart announced today that it will undercut iTunes by five cents a song in its new MP3 download service. Still without cell phone, I was dragged into the iPod age a while back. So what I want to know from somebody who has the time and skill to do it, how does Wal-Mart compare? Same or better selection? Are there advantages to using iTunes over Wal-Mart? Will it be easy to buy Wal-Mart and load an iPod? These probably would sound like silly questions to any 11-year-old, but I'm not so technoficient as they.
