Well, apart from NTFS being more stable (I've had a couple of FAT32 drives lose their table of contents, and they're still sitting here for me to recover the data at some point), I haven't really found any great advantage to NTFS over FAT32. Going over the 137gb barrier is good, but unless you've got a hard drive bigger than that, (I do video editing, so I need NTFS) then you don't really need NTFS - it's less compatible, harder to recover if it dies (you need another XP machine to put the drive in, whereas Linux can write to FAT32 partitions) and overall, not necessary unless you're after the extra stability or the extra space, IMO. :-)
