I personally see little difference on a regular consumer level system... (performance wise)
the real pros/cons are all on paper and I think for the average user, sticking to FAT32 would just be easier in the end...
If you've never used NTFS before, there is no reason to switch IMO unless you are running an NT server or something.. FAT32 under win2k has always worked well for me, and all files and such are completely compatible with other PC's like win9x obviously so it just makes things easier.
sure there are reasons NTFS is better, but I believe they are negligible.. surely you will hear differently!
