I know about the other third-party options out there, this is more to do with the native stuff that comes bundled from Apple. For years Snow Leopard has had notoriously bad NTFS read-write support hence it was disabled by default. We could enable it like this, but it was dangerous at best. So, has this improved in Lion, or is this still a neglected dangerous feature?
I haven't seen any credible reports that NTFS write support has improved with Lion. It was in Snow Leopard and still is disabled natively.
As, it's not supported by Apple, getting a good third party plug in to enable that feature is as mandatory with Lion as it was with Snow Leopard.
You can still just remount it as rw unless its dirty flag is set (it is if it wasn't unmounted properly last time). I never had problems, in my opinion you don't have to spend money on a third party plugin.– bot47Feb 6, 2012 at 16:56
