Another learning curve arrives...
I finally made the decision to switch to Apple Final Cut Pro.
I made the decsion for three reasons:
1. All the filmmakers that I'm working with are using FCP.
2. After going to the confusing Adobe site and trying to figure out what I'd have to buy to upgrade my current version of Premiere Pro, I concluded that Adobe's latest version of Premiere would be almost twice the price of FCP!
3. Adobe's past practice of changing user interfaces radically when they upgrade Premiere.
To run FCP, I'm buying a used Apple G5 computer with dual 2.3 Ghz processors and 1.5 gig of RAM.
