Reply to Kontrol F1 if already getting Traktor?

So I was going to get Traktor Pro 2 (which is now like $86) in the next couple weeks and update to 2.5...however I just discovered that if you get the Kontrol F1 it comes with Traktor Pro 2 (well, I guess by then it'll be 2.5).

If I already need the software, should I just go ahead and get the controller? It looks like its used for samples, remixing, etc...I'm still doing my research; but I'm currently running a Mixtrack Pro, so I figured maybe this would spice it up a bit?

What exactly does it do? I see a few threads on it but some of the terminology is over my head (I've only started 2 months ago).

Thanks in advance for your time!
