Good advice, however, history may show that this is like saying if you fall in the ocean, hold your breath. You eventually have to breath.
I went through this in the last of the System 9 days with my Macs. Among other things, I have a small production studio and was running Digital Performer with installed MOTU PCI cards.
I just didn't upgrade (very unlike me, I wanted to upgrade). However, slowly but surely, other programs came out with upgrades I wanted or needed or I saw a new program I wanted or needed that just wouldn't run on System 9 anymore. So onto OSX on my PowerPC..... and then upgrades and new programs demanded that I move to an Intel machine.... so I did that.... hmmmm.... come to think of it, maybe there is a lot of thought to making hardware and software obsolete.
What I'll probably do is never upgrade this Intel MacBook Pro computer and will keep FCS running as long as I can, or until someone comes out with a "converter" utility to get all my projects into something else (Premiere or maybe Apple will have something better by then). When I see a program I've GOT to have, I'll buy a new computer.
BTW.... My video projects are typically multi-camera shoots of my music bands -- 3 to 6 camera shoots. Then I take the footage and use the FCS Multicam feature to edit it all together. I gave FCPX an objective review, but that is at least one of the features (multicam) that is missing. And for me, and many others reading from the various threads, the number one reason not to make the move is that all the work I've done for the past 10(?) years on FCP (since v1.0) will be gone.
What I can't understand is that there have been MAJOR motion pictures edited on FCP and it seemed like Apple would take over that world. So what do they do? Kill, not slowly, not gracefully, but in an off-hand announcement that FCPX was better and there will be no more FCP. I actually thought I read that wrong the first time I saw that..... What's that about, anyway? FCPX reminds me more of an amateur video editing program. Maybe that's the crowd they are going after, but then just call it something else like iVideoFun and continue to support FCP.
