I've owned it for many years simply because I buy a lot of stuff to help me use my lone Mac in the raging sea of Windows and NTFS servers. But now I am in an environment about half-and-half, where everyone is on the same shared Windows NTFS drive, and everyone is fine. I have not tested everything, but it would appear that the only thing I could not to without Paragon NTFS was (for instance) format a thumb drive in NTFS. What else am I missing?
