I got a kick out of this project to create a RAID array out of a set of iPod Shuffles. This is one of those things that, of course, should work, but it's always kind of fun to see it actually done.
I had a chance to play with an iPod Shuffle for an extended period of time recently, after a colleague purchased one. I'm always amazed at Apple's attention to detail (and so was my colleague, who isn't an Apple person). The sound is outstanding as well.
