Spent a couple of hours with this today.
As always Eli does a great job. There is quite a bit of repeat material if you are long time X series user. Sometimes it is helpful to go back over stuff you may have forgotten...okay I may have forgotten. None the less you can always jump ahead to the new features without the "How to set up a sound card' part.
Overall I will say this: I was a bit on the fence on this upgrade but after viewing this and seeing that it wasn't just marketing hype I have to say that X3 looks pretty impressive. I'm thinking an upgrade is in order.
