As I see it, you have to take a look into the future and start developing a game plan as to what your business/workflow will look like in 5 years. What do you see yourself looking towards as far as the tool you will be using? Are you going to switch to AVID/Adobe or hold onto Final Cut Pro 7 for as long as possible?
Also, are you worried about Apple abandoning traditional computing in favor of iOS-based devices? What are you looking at doing to future-proof what you need and for adapting older projects to still be usable down the road?
