I have a mac and I have a pc
mac runs limewire and itunes way better and without viruses
don't get me wrong I hated mac too until I observered this myself.

Soo now I use my pc for everything else except my music
the mac handles that now

plus without lime running on my pc in the background all the time everything goes 10 times faster.

All in all to be fare if there happens to be a crash or error on a mac since its linux based your best bet is to just turn it off and listen to your hard drive skip once then hope it boots again no viruses with mac even if you download the 443.9kb file that comes up with every search in limewire get a mac do it on purpose and breath easy nothing will happen mac still sux for everything else
