not true. 10.3 can read NTFS, but cannot write for some stupid reason. trust me, I know. I have to use the f*cking pieces of sh*t everyday when transferring files from my PC to MAC at my office. it is rumored that the new 10.4 OS X will be able to write but by that time I will have already have gone a-wall and destroyed all the G5s with an AK-47.
