It's a bloody waste, couldnt get it to work on my nano, and why would you want it on your mini? Black and white video? However if you get a new ipod later, it would be cool to put ipod linux on there and do some of the other cool things.
I've seen a video of someone who did that with a 4G B&W iPod. They got it to play video. But the display only shows 4 shades of grey, so why would you want to? Not worth it IMO.
