I've been using Limewire for about a month on a G4 350mg (pci) I had almost no problems with it. Since I went to 1.6 I've had a few problems with the options, and the success rate for uploads went from about 60% in 1.4 to 10% in 1.6. But all in all I've been very happy with it. (A few times it refuses to quit and give me back my computer without a restart, but I'd just have to go back to work anyway) And like a lot of other Mac users I am grateful the developers of Limewire acknowledged us at all. And as is mentioned elsewhere in this thread, OSX should make us lose our dread of the words "Java-based" Thanks!
