If you installed Mac OSX into a UFS partition (what I din't make clear above when using strictly OSX), then defragmenting would be a waste of time since the unix file system handles file fragmentation just fine. If you have HFS or HFS+, you need contiguous space for movies and such or use a lot of Classic apps, then defrag. Norton is best if only for it's speed over Plus Optimizer.
PlusOptimizer does take FOREVER, you're right. i have to leave it running all night usually. i am not sure how much of that it takes, but it's at least a 3-4 hour process on my 60 GB hdd.
