I am very new to video - I bought FCP from BHP photo back in March for $749. I started learning it. I was doing pretty good then X came out. I decided if I am going to learn it might as well be the new software. So I put FCP on Ebay in July when Apple quit selling it. I sold it for $1400!
I turned around and bought X, Compressor and Motion. I could not be happier. With the extra $1000 I turned around and bought a Canon XF100 which is the best camera I have ever used I love it. Got a $3000 camera for $2000. I wish X worked with Cannon Codec but it is what it is... maybe on the upgrade. But, I love the camera so much I will deal with it.
So for me a HUGE WIN. I am very happy with X. It does crash sometimes, it is the first version, but most of the time my work is saved. I am editing on a 3.33 6 Core MP with 16GB's of Ram. I have to 120GB SSD that I do my editing through then move the project to 7200 drive when done.
I love the look and functionality. I do video for my own business and it works great for me. I also love motion I am now doing my own graphics, lower 3rd's logo's etc...
I did not have ANY video experience and now people are coming to me, saying how are you doing that and I am saving tons a money. My videos used to cost me $1500 - $3000 each. I am big on getting quality audio. I have a bunch of Mics. I use a shotgun outside and a lav normally. I came upon a cool condensor that I will use indoors above me. If I am in a pinch I will use my Senn with a countryman and the mic is actually on my face can't get closer then that.
I am one of the few VERY happy X users and I am still learning, Motion is just awesome. Love it too! I have two ACD's and I have X on one and motion on the other it just rocks

Jam some Metallica and good to go
Just saying over the last 6 months I have probably saved $40,000 thanks to FCPX and I am learning a skill that I actually enjoy.
There are some good tutorials out there.
Good luck, hopefully you can sell it and get a win like I did or if you keep I don't think you can go wrong learning X, been a great experience for me and have not looked back.
