If I used Logic, I'd be looking for an alternative. I know that Final Cut X has gotten better but it could have just as easily not gotten better. We didn't know. We still don't know. It could go away.
I am a working food photographer who dabbled in filmmaking and now have a "hit" indie film called The Battery.
From the filmmaking side, the fall of Final Cut Pro was genuinely shocking. I don't mean the program itself, I mean its dominance. A few years ago it was pretty much the indie standard... Today, I haven't met a single real, working filmmaker that hasn't made the jump (mostly to Premiere, but Avid on the higher end). I am close with over a dozen filmmakers that our movie traveled the festival circuit with, all with released and distributed films, and not a single one uses Final Cut today, yet cut their teeth using it years ago.
In the photography and design world where I make my real living, the loss of Aperture won't make much of a shockwave, which is probably why it's being neutered and made into a free consumer app. Simply put, I have never met a paid photographer or designer who isn't doing their work in Adobe products. There are strong opinions on Adobe's business model on here, but I feel these are coming from consumers and prosumers. There simply aren't any career professionals that I have met that use anything other than Lightroom and Photoshop (together) or Bridge and Photoshop. I have worked with dozens of clients in the print world and every single one required Adobe files, be it layered Photoshop files or InDesign files for longform projects. (Quark is dead.)
The writing was probably on the wall for Aperture the day that Lightroom was first released. It still doesn't have the greatest integration with Photoshop, but having any integration with it at all was going to eventually make Adobe the victor in the pro world. Pros use Photoshop, it's that simple. Lightroom hit quick enough that pros that were using Aperture had no real allegiance to it.
There was a true allegiance to Final Cut though, which made filmmakers continue to go out of their way to add After Effects to their workflow. When Apple released FCX, After Effects integration (much like Photoshop with Lightroom) sweetened the deal for filmmakers to switch to Premiere.
Apple still has one dominance in the filmmaking world. My film has been distributed in 15 countries and the distributors all request the film in ProRes HQ. ProRes is most definitely still the standard for delivery. In my admittedly varied career(s) ProRes is the one thing that actually makes me still consider buying a Mac.
Because, yes, I still work on Windows. I am not a troll, just a member here because I genuinely love the iPhone. So in a way, I'm kind of the problem with Apple's more consumer approach since their success with iOS. Apple has me hook line and sinker with iOS devices, because they need to "just work" but for whatever reason, I still like my work machine to feel like work. I like to open it up and upgrade and tweak things. Windows 8 blows, but I turned it back into Windows 7 (cosmetically) in 5 minutes.
With filmmaking, I genuinely thought I HAD to go Mac, but the Final Cut debacle happened right when I was looking to upgrade to an editing machine. At that same time, the old Mac Pro tower was overpriced component-wise. Knowing I would be going with Premiere, it allowed me to custom build a PC, save several hundred dollars, and not feel like I was behind the rest of the industry. ProRes turned out to be the only hang up, but thankfully there are several freeware programs that allow me to convert uncompressed files to ProRes HQ for final delivery.
I suppose the point of my post was that exclusive software can be an ace in the hole (look at game systems), but Apple has pretty much given up on that in the Pro world. That said, clearly they have instead focused on their most important exclusive software, OSX and are making it more enticing to the masses with every update. 95% of the time my computer is on, it is in either an Adobe program or Chrome, so I'm happy and just keeping up on this stuff for a few years from now when I want to upgrade machines.
