Disregard what others say (would you let peoples opinion of your spouse/significant other effect your relationship? Extreme example but whatever). People don't like change, especially the old (but not always), I know how to use a variety of NLE's and after using FCP X using other NLE's is like riding a bike vs riding a motorcycle...going to FCP X for me was like going to OS X for the first time from windows, I was SOOO frustrated with OS X at first but then I stopped over thinking and realized that in OS X everything wasn't burried in 20 menu options it was right where I expected it to be, right where I would have guessed. FCP X was the same thing for me. Don't get me wrong I'm currently learning Avid MC7, its not HORRIBLE but allot of it is just stuck in old archaic crap mode, and where something in Avid MC takes 3 or 4 clicks in FCP X it takes 1 click if it hasn't already done it already. Media management in FCP X is great too, I don't want to say its better than Avid because with Avid collaboration is MUCH easier than FCP X (although I haven't collaborated with Avid on any major projects aside from small videos with minimal edits needed).
Anyways, the FCP X thing burned allot of editors from the first version of it since it really was barely usable (no XML's, and a bunch of other stuff) and I think peoples memories are just too long and unforgiving (rightfully so, you get paid to edit you don't want to screw up something, "if it aint broke dont fix it!"). HOWEVER 2 years later that stigma has gone down and I'm hearing about editors using FCP X, even some professionals, their posts online are slowly adding the X at the end of "I was using FCP" so I think the "shame" is going away hehe. Regardless there are some very high end workflows that utilized FCP X entirely, Apple has some of them show cased on their website if your curious. Don't be ashamed because if you can cut a video in 15 minutes on FCP X and someone is on Avid Symphony 3 and taking an hour to do the same who's the faster editor now?
I loved video and film editing since I was a kid but I knew what the software was like and I just plain had no desire to put up with the bag of hurt of NLE's when I was younger but now with FCP X I just get to work and I'm not worrying about my NLE limiting me. I just throw the media in and start cutting and its like typing a paper of up.
