Limewire is By Far the best p2p program available! Anyone who uses Kazaa or Morpheus has no idea about the crap they put on your computer. Aside from selling your information to anyone on the internet...that's a whole different topic! Something like 70% of the files that come from users of K&M are laden with viruses and corrupt.

The key to using Limewire succesfully, is to know 'which' files to download. Some people search for a song, one comes up and they don't bother to look at the size, or type of file it is. Boom, virus, corrupt! A song will never be any less 3Mb (unless it's a shorty).
So when you download a song, look at the size and file type. If it says 134K, don't download it!! Period!

As far as 'speeds', it's all your connection or the other guys...has Nothing to do with this software! Period!
