Actually, what I did, was I found a bunch of useful config and boot files that I can use with a loader on my Wii, and I can turn it into a Linux-based powerpc. It's quite nice and has some unique features, like a Wii Controller Daemon. I don't use a USB mouse, but if I had one, I'd use it over the Wii controller as it won't drain my batteries. But I have to admit that the on-board browser, Dillo, really sucks. It is breaking PC's themes beyond recognition and it won't retain cookies, logging me out every odd session or so.
