I'm using Nero 5.0.3.8 right now, and love it.
Where it says that current users of Nero 5 will probably be able to upgrade for free probably refers to users that purchased the software and not to those that received it bundled with hardware.
The WAVE EDITOR feature seems very nice and i can see it being a rather nice and handy utility for me, that I would use a fair amount.
The VIDEO CD CREATION feature also seems excellent and very comprehensive though of little use to me personally.
The incorporation of CD Speed99 into Nero is great IMHO, as I use CD Speed99 myself, so that removes one program needed to be installed if it's bundled with Nero.
Overall it looks like quite few additions to the software to extend it's usefulness.
Anyone have any idea when it is due to be released?
