i think the question you should be asking yourself isnt IF you should change format, but rather WHY you want to change it.. i only ask this because you stated you are unsure if you want to change for fear that you might want to change back later.

As a broad statement, NTFS partition is really only needed for extra security and other features that you are highly unlikely to use on a typical home system. also NTFS cannot be read by Windows OS lower than 2k.

i would leave it as a FAT system for no other reason than "whats the point?"
