Oh and....
Debian + LXDE is a whole different universe than Lubuntu. Like, way different. It runs better, is light years more stable, and has much less ridiculous 'buntu nonsense running in the background. "Software Center?" Its called Synaptic. Or Apt. Debian does take some configuring, which was the main selling point of MintPPC, ie, he did most of the config for you. MintPPC has been stuck for two years at Mint 11, which is not the end of the world, cause you can always put a more modern Debian underneath it, but...the dream of a truly easy to install, pleasure to use PPC Linux is probably gone.
Wildy? Anyone?
